Extends the SVG projection line deduplication introduced earlier with
several new cases:
**Containment adjacency (inner element inside outer)**
- The original shared-vertex check failed when an inner element's corners
lie on edges of the outer element rather than at corner vertices.
- Added vertex-to-edge proximity check using point-to-segment distance.
- When one AABB is fully contained within another, skip the dominant-face
normal check: a short/flat inner element's largest polygon is its
top/bottom face, giving a spurious perpendicular normal.
**Anti-parallel normals (mirrored wall faces)**
- Two adjacent wall sections can have opposite face normals (+Y vs -Y)
while still being on the same plane. The original `abs(dot)` check
correctly identifies them as parallel, but projecting onto each
object's own normal produced mirrored plane-position values that never
matched.
- Fixed by projecting both objects' vertices onto the same reference
normal (n_a) when computing face-plane positions.
**Parallel offset walls (false positive rejection)**
- Two walls with identical orientations but on different parallel planes
(e.g., offset walls meeting at a corner) were incorrectly accepted by
the normal-direction check alone.
- Added face-plane position check: after confirming normals are parallel,
verify at least one face-plane position of A (projected onto the shared
normal) matches one of B within tolerance.
**L-shaped wall split segments (collinear overlap)**
- An L-shaped wall's boundary at a shared interface can be split into
multiple sub-segments (one per notch side), while the adjacent simple
wall has a single full-length segment covering the same edge.
- Exact endpoint matching always failed in this case.
- Extended `lines_match` with a collinear-overlap check: axis-aligned
segments on the same line with overlapping extents (beyond a trivial
point touch) are now treated as the same physical edge.

Adds `remove_coplanar_boundary_lines()` to operator.py (Bonsai uses this
path, not draw.py's main()). After `merge_linework_and_add_metadata()`
assigns material CSS classes, this post-processes the SVG to delete
projection line segments that appear in two or more adjacent, coplanar
elements with the same material and presentation style.
Key design decisions:
- Material identity: compared via sorted IFC material ID tuples from
`get_materials()`, not CSS class names — avoids false matches between
unrelated `material-null` elements.
- Presentation style identity: compared via IFC IfcPresentationStyle IDs
from `StyledByItem` on geometry representation items — handles elements
with no material but distinct visual styles.
- Physical adjacency: confirmed by a 3D shared-vertex test (tol=0.01 m)
after a quick AABB guard, rejecting elements whose 2D projections
overlap but sit at different depths.
- Coplanarity: determined by the dominant (largest-area) face normal of
each Blender mesh object — area-weighted averages are unreliable for
slabs whose equal top/bottom faces cancel out. Folded walls sharing an
edge but meeting at an angle are correctly rejected (normal dot ≪ 1.0).

- Add Anthropic prompt caching (cache_control on system prompt and
tools) to reduce repeated token costs by ~90%
- Truncate large tool results in conversation history (2000 char cap)
to prevent context bloat from ifc_tree/ifc_select responses
- Add sliding window (40 messages) on conversation history, trimming
at user message boundaries to avoid breaking tool-call sequences
- Default "New IFC" button to IFC4X3 schema instead of IFC4
- Constrain ifc_new schema parameter with enum to prevent invalid
schema strings like "IFC4X3ADD2"

Parse ifcmerge JSON output and display a per-conflict breakdown in the

conflicts without committing. Add SelectConflictEntity operator to
select and frame the conflicting object in the 3D viewport.

A degenerate edge (zero-length segment) caused an early `return`
of a tuple instead of continuing the loop, resulting in a
TypeError when snap.py iterated the result and tried to assign
`point["group"]` on a float.

Add a provider selector (OpenAI / Anthropic) to the ifcchat web UI,

When a remote branch tip is checked out (resulting in detached HEAD),
the new-branch name field is now pre-filled with the local equivalent
of the remote branch name (generating a unique suffix if that name is
already taken), so the commit button is immediately usable.

This version has some functional differences:
- Structured JSON error message instead of free text (on STDOUT not STDERR)
- New --prioritise-local flag to control which side wins in merge conflicts (not used by Bonsai yet)
- IfcLocalPlacement conflicts now auto-resolve instead of failing the merge (partial solution to #6885)
- Float values are normalised when comparing entities (workaround for #7696)
Include bonsai_git_branch in get_debug_info(). For dev environments
using the GitPython-based update_commit_data() path, the branch is
read from repo.active_branch.name. For built extensions, a 7777777
placeholder is replaced at build time via the Makefile, matching the
existing pattern for bonsai_commit_hash and bonsai_commit_date.

Two bugs introduced in 31b571322:
- SnapObj assumed obj.data is always a Mesh; non-mesh
objects (empties, lights, etc.) have obj.data = None,
causing an AttributeError on obj.data.edges.
- view3d_utils was used but never imported.
