closes #6235 - Add copy toggle to CAD offset

Add a "Copy" option to bim.cad_offset. When enabled (the default) it offsets a new copy of the selected edges as before; when disabled it moves the existing edges to the offset location instead. The toggle is exposed in the CAD tool's Offset panel and the operator redo panel. Generated with the assistance of an AI coding tool.

-Docker build environment
-========================
-
-This is a small utility to make it easy to compile a perfect `_ifcopenshell_wrapper.cpython-*-x86_64-linux-gnu.so`
-files.
-
-The reason for this tool is that I was trying to follow the web page directions, and my build was behaving differently
-to the release builds. Eventually I concluded that the differences between toolchains on the RHEL based rocky9 image
-and Ubuntu were just too great. Getting the build setup was already a lot of trial and error, so I thought I'd spend
-more time trying to reuse the github actions that perform the build, using a utility called `act`. I learnt a lot, in
-particular how much time, energy, and bandwidth Github waste. I also realised I was most of the way to a regular docker
-setup anyway, so I might as well just do that. So I've deconstructed all the github action steps, and turned it into
-a local docker build environment that uses the exact same base, tools, libraries, and build command/flags etc.
-
-Right now a Github action will:
- launch the rocky9 base
- upgrade all the packages
- install a bunch of extra tools
- do a recursive checkout of your repo
- checkout the build repository
- unpack dependencies
- run the build script, making all python versions (5? right now I think)
- create the .zip release files
-
-And it does _all_ of that _every_ time. This is not a fault of the action writers - it's just how Github seems to work.
-
-These dockers tools do the following differently, and it's actually a bit more powerful too:
- build the base image once.
- update the packages once.
- install the extra tools once.
- the repository is the one on your host, that gets bind mounted in the container as the working directory.
- by adding an environment variable to .env, restricts to compiling for just a single python version.
- when the build is finished the created files are right there under your local repositry (but not added to git) for
-  ease of access
- each repository can have it's own build environment container.
- the image is shared between those environments.
- the containers share the ccache, so additional envs should get a helping hand.
- it has a simple set of user friendly commands to drive it all.
-
-For example:
-``` bash
-# To see the commands (a superset of docker compose commands)
-./ifcos_env
-
-# Enable autocomplete of commands
-source .ifcos_env
-
-# First time commands
-./ifcos_env create
-./ifcos_env up
-./ifcos_env build
-
-# install and test library
-# find an issue
-# edit code
-./ifcos_env build
-
-# and so on. When done stop and optionally delete the container
-./ifcos_env stop
-./ifcos_env remove
-```
-
-To limit the build to one python version just add
-``` bash
-PY_TGT=py-311
-```
-or whichever version your Blender requires.
-
-You might see UNIQUE_ID in the .env file too. This keeps containers for separate folders, separate.
-
-System requirements
-1. Linux-x64 only at this time.
-2. Docker and docker-compose need to be installed.
-3. Have a good amount of disk space. (image is in /var (typically the root partition) and will be about 1.7 GB)
-4. The build action will create about 10GB in your repository folder. Make sure this partition is spacious
-   particularly if you intent on having multiple clones building.
-5. ... I think that covers most of it.

-name: ifcopenshell-docker-build
-description: >-
-  Build a real ifcopenshell_wrapper (.so + .py) and IfcConvert locally via
-  the docker/ifcos_env toolchain, then wire them into a checkout for
-  running C++-dependent parts of the test suite (geometry, the SWIG
-  wrapper stub, the C++ parser). Use whenever a task needs to compile
-  IfcOpenShell's C++ core rather than just read/patch source - e.g.
-  reproducing or fixing a bug in src/ifcgeom, src/ifcparse, src/ifcwrap,
-  or validating util/scripts/validate_stub.py against the actual
-  generated wrapper.
---
-
-# Building IfcOpenShell locally with docker/ifcos_env
-
-`docker/` mirrors the project's GitHub Actions build environment locally,
-in a persistent, non-root container with ccache so repeat builds are fast.
-See `docker/README.md` for the design rationale. Pure-Python changes don't
-need any of this - only reach for it when you need a real compiled
-`_ifcopenshell_wrapper*.so` or `IfcConvert` binary.
-
-## Placement
-
-This `docker/` folder must live as a direct child of the repo root you want
-to build (sibling of `src/`, `cmake/`, etc.) - `compose.yaml` and
-`ifcos_env` resolve the repo via `../` relative to wherever `docker/`
-itself sits, and bind-mount it into the container. If you're setting this
-up in a fresh clone, copy the whole `docker/` directory there first.
-
-## Setup
-
-```bash
-cd docker
-./ifcos_env create   # build the image (shared by name across all your clones/checkouts, so usually instant after the first time anywhere)
-./ifcos_env up        # create + start the container, clone/unpack the third-party dependency cache (~10GB, one-time per container)
-./ifcos_env build     # full build: all deps + IfcParse + IfcGeom + IfcConvert + the Python wrapper, for one Python version
-```
-
-`PY_TGT` and `UNIQUE_ID` live in `docker/.env` - `PY_TGT` (e.g. `py-311`)
-restricts the build to one Python version instead of building five;
-`UNIQUE_ID` is a hash of the folder path, recalculated on every `up`, so
-each checkout gets its own container/volumes automatically.
-
-A full first build takes ~1.5 hours (mostly compiling IfcOpenShell's own
-C++, not the cached third-party deps). After that, ccache makes incremental
-rebuilds of a couple of touched `.cpp` files **under a minute**.
-
-## Container lifecycle
-
-The container is long-lived (`sleep infinity`) so exec'd commands and
-ccache state persist between builds. Commands map directly onto Docker
-Compose's own container-vs-image distinction:
-
-```bash
-./ifcos_env up         # create the container if it doesn't exist, then start it (runs ready_repo too)
-./ifcos_env stop       # stop the container, keep it around
-./ifcos_env start      # start it back up (same container, same filesystem layer)
-./ifcos_env restart    # stop, then start
-./ifcos_env down       # remove the container (and its network) entirely
-./ifcos_env recreate   # down, then up - a fresh container
-```
-
-Named volumes (`ccache`) and the bind-mounted repo/`build/` are unaffected
-by `down`/`recreate` - only the container itself goes away, and `up`
-recreates it from the image.
-
-## Fast iteration
-
-Pass a target to `build` to skip the parts you don't need:
-
-```bash
-./ifcos_env build IfcConvert           # only the executables (IfcConvert, IfcGeomServer) - skips the Python wrapper entirely
-./ifcos_env build IfcOpenShell-Python  # only the SWIG Python wrapper - skips executables entirely
-./ifcos_env build                      # no target = everything (needed the first time, or after touching shared headers)
-```
-
-Use this to keep the edit -> rebuild -> test loop fast when debugging: if
-you're only touching `src/ifcgeom/`, build `IfcConvert`; if you're only
-exercising the Python API, build `IfcOpenShell-Python`.
-
-## Where the artifacts land
-
-Build output goes to `<repo_root>/build/Linux/x86_64/install/` on the host
-(bind-mounted, not just inside the container), owned by you (see
-"Container user" below):
-
- `ifcopenshell/bin/IfcConvert` - the CLI binary
- `python-<version>/lib/python<X.Y>/site-packages/ifcopenshell/_ifcopenshell_wrapper*.so`
-  and `ifcopenshell_wrapper.py` - the compiled wrapper + its generated
-  Python glue
-
-## Testing against a checkout (automated / AI-driven)
-
-`_ifcopenshell_wrapper*.so` and `ifcopenshell_wrapper.py` are already
-gitignored under `src/ifcopenshell-python/ifcopenshell/`, which is exactly
-where a normal in-tree build would put them - copy the two files there:
-
-```bash
-SRC=build/Linux/x86_64/install/python-3.11.8/lib/python3.11/site-packages/ifcopenshell
-cp "$SRC/_ifcopenshell_wrapper.cpython-311-x86_64-linux-gnu.so" src/ifcopenshell-python/ifcopenshell/
-cp "$SRC/ifcopenshell_wrapper.py" src/ifcopenshell-python/ifcopenshell/
-```
-
-Then, to run the test suite against it:
-
-```bash
-export PATH="$PWD/build/Linux/x86_64/install/ifcopenshell/bin:$PATH"   # for IfcConvert-dependent tests
-cd src/ifcopenshell-python/test
-PYTHONPATH="$PWD/.." python3.11 -m pytest -p no:pytest-blender .
-```
-
-(`-p no:pytest-blender` avoids the pytest-blender plugin trying to find a
-`blender` executable and failing collection entirely, even for non-Blender
-tests.) You'll need the matching Python version's `pip install`s too
-(numpy, shapely, isodate, lark, tabulate, pytest, ... - whatever the
-modules under test import) since this is a bare interpreter, not the
-project's pixi env.
-
-**This is the pattern to use for automated or AI-driven verification.**
-Don't use `try` (below) for that - it overwrites files in a real, live
-Blender installation, which isn't something an automated/AI workflow
-should ever do without the human explicitly asking for it in the moment.
-
-## Testing in Blender itself (human only)
-
-`try` copies the built wrapper straight into your actual Blender/Bonsai
-extension install, for manual in-Blender testing:
-
-```bash
-./ifcos_env try
-```
-
-It reads `BLENDER_USER_RESOURCE` from `.env` - set this to wherever
-Blender's user resource folder for the Bonsai extension actually lives on
-your system, which depends on your own Blender setup:
-
-```bash
-# in docker/.env
-BLENDER_USER_RESOURCE=~/.config/blender/bonsai/
-```
-
-`try` figures out the built Python version from `build/.../install/`
-(disambiguating with `PY_TGT` if more than one version was built) and
-copies the wrapper to
-`$BLENDER_USER_RESOURCE/extensions/.local/lib/python<X.Y>/site-packages/ifcopenshell/`.
-
-## Container user
-
-The image runs as a non-root `builder` user, UID/GID matching your host
-account (passed as `--build-arg` by `create` from `id -u`/`id -g`, so it
-adjusts automatically - no manual flag needed even if you're not 1000:1000).
-Files the build creates under the bind mount come out owned by you, not
-root. Passwordless `sudo` is available inside the container (e.g. via
-`attach`) for the rare case you need root for something ad hoc.
-
-If you're picking up an existing checkout that was previously built with
-an older, root-based image, you may hit `Permission denied` the first time
-you run `up`/`build` under the new image - `build/`, `.git/modules/`, the
-`ccache` volume, `output/`, and `build.log` can all be left root-owned from
-before. Fix it once via the container's own root (no host `sudo` needed):
-
-```bash
-docker exec -u root -w /__w/IfcOpenShell/IfcOpenShell <container-name> \
-    chown -R "$(id -u)":"$(id -g)" .git/modules build output build.log /ccache
-```
-
-(`<container-name>` is `ifcopenshell-<UNIQUE_ID>` - see `docker ps -a`.)
-
-## Other things worth knowing
-
- **Linux x64 only.** `compose.yaml` pins `platform: linux/amd64`; on an
-  ARM host (e.g. Apple Silicon) this build isn't available.
- **The final "Package .zip archives" step of `build()` has a pre-existing
-  bash syntax error**, unrelated to compilation - the actual build already
-  succeeded by that point (look for `Built IfcOpenShell...` in the output),
-  so this is safe to ignore if you only need the raw artifacts under
-  `build/.../install/`, not packaged release zips.
- **`test_mmaped_stream` and similar `USE_MMAP`-dependent tests will fail**
-  against this build - `nix/build-all.py` is invoked with `USE_MMAP=OFF`
-  here. Not a bug in your code if you see it fail.
- Only the bind-mounted `<repo>/build` lives on the host filesystem your
-  repo is checked out on. Anything the container writes *outside* that
-  mount lives in the container's own writable layer under Docker's data
-  root (commonly `/var/lib/docker`, i.e. usually your root partition) -
-  keep an eye on `df -h /` if you're running several of these containers
-  at once.

-"""Generic face-quad resize gizmos for any axis-aligned local box.
-
-This module contains the box-agnostic core of the interactive
-face-resize gizmos: two Gizmo classes (a near-invisible click target
-welded to each face, and a thin colored edge outline), a per-redraw
-orchestrator that places six of each on a box, and the pure one-sided
-resize arithmetic. None of it knows about IFC, clip boxes, or
-``BIMSceneClipBoxProperties`` — a future camera-view-box adapter can
-reuse the same classes and helpers.
-
-Consumer contract — the adapter group must:
-
-1. Create six ``BIM_GT_box_face_quad`` and six ``BIM_GT_box_face_outline``
-   instances at ``setup()`` time, in :data:`FACE_ROUTES` order, and bind
-   each quad's ``move_get_cb`` / ``move_set_cb`` to closures that read
-   and mutate the box's host (e.g. an Empty's ``location`` / ``scale``).
-2. Call :func:`apply_face_quad_layout` from ``refresh()`` /
-   ``draw_prepare()`` with the box's local-frame ``bmin`` / ``bmax``,
-   the host's ``matrix_world``, the OBB rotation as a 4x4
-   (``Matrix.Identity(4)`` when the rotation rides in ``matrix_world``),
-   and the current ``region`` / ``rv3d``.
-3. Implement ``_lock_for(active_gz)`` / ``_unlock_all()`` on the group
-   for drag mutual exclusion; the quad's ``invoke`` / ``exit`` call them.
-
-The resize arithmetic in :func:`compute_face_resize` is pure: feed it
-the modal scalar plus drag-start snapshots and it returns the host's
-new scale-on-axis and new origin location.
