fix #7537 - Layer thickness correct when slab is rotated and few other features...

- Add dual-rotation support for AXIS3 slabs (IFC angle + object rotation)
- Fix profile editing to display horizontal projection for tilted slabs
- Fix AXIS2 layer slicing to use local extrusion direction for walls
- Fix ChangeExtrusionDepth to refresh geometry after depth changes
- Remove rotation lock on slabs to allow free rotation
- Fix undefined variable bug in add_slab_representation.py

-# AGENTS.md
-
-Guidelines for AI coding agents contributing to IfcOpenShell. This file is
-intended to be read by all AI agents regardless of platform (Claude Code,
-Copilot, Cursor, etc.) in addition to any tool-specific configuration files.
-
-Human contributors using AI tools should also read this document carefully,
-as they are responsible for ensuring their contributions comply with these
-guidelines.
-
-## Project Overview
-
-IfcOpenShell is an open source library for working with Industry Foundation
-Classes (IFC). It provides C++ and Python APIs, geometry processing, and an
-ecosystem of tools including IfcConvert and the Bonsai Blender add-on.
-
-## Licensing
-
-All contributions must be compatible with the project's licensing:
-
-- **Library code** (everything except Bonsai): **LGPL-3.0-or-later**
-- **Bonsai** (`src/bonsai/`): **GPL-3.0-or-later**
-
-There is no Contributor License Agreement (CLA). By submitting a pull request,
-you agree that your contribution is licensed under the applicable license above.
-
-## Indicating AI-Generated Code
-
-Contributors must clearly indicate when code has been generated or
-substantially written by an AI tool.
-
-### Commits
-
-Commits that modify existing code must include a note in the **body** of the
-commit message (not the subject line) indicating that the change was
-AI-generated. For example:
-
-```
-Fix off-by-one error in element iteration
-
-The loop termination condition was incorrect when processing
-IfcRelAggregates relationships.
-
-Generated with the assistance of an AI coding tool.
-```
-
-### New Files
-
-New files that are AI-generated must include a comment near the top of the
-file indicating this. Use the appropriate comment syntax for the language:
-
-```python
-# This file was generated with the assistance of an AI coding tool.
-```
-
-```cpp
-// This file was generated with the assistance of an AI coding tool.
-```
-
-### Pull Requests
-
-Pull requests containing AI-generated code must indicate in the PR description
-which parts of the contribution are AI-generated. If the entire PR is
-AI-generated, state that clearly. If only specific commits or files are
-AI-generated, identify them.
-
-## Pull Request Guidelines
-
-### Scope and Size
-
-- Each pull request should address a **single issue or feature**.
-- Do not mix unrelated changes (e.g., bug fixes with refactoring or style
-  changes) in the same PR.
-- Large pull requests should be broken down into **multiple small, standalone
-  commits** that are each easy to review independently. Rewrite commit history
-  for this purpose if necessary.
-- PRs that are minimal, focused solutions to a specific problem are much more
-  likely to be accepted.
-
-### What to Avoid
-
-- **Over-engineering**: Do not add features, abstractions, or configurability
-  beyond what is needed to solve the immediate problem.
-- **Scope creep**: Do not make changes to files or code that are not directly
-  related to the task at hand.
-- **Unnecessary additions**: Do not add docstrings, comments, type annotations,
-  or error handling to code you did not otherwise need to change.
-- **Cosmetic changes**: Do not reformat, rename, or reorganize code that is
-  unrelated to your change.
-
-## Commit Messages
-
-- The **subject line** must be **50 characters or less**.
-- Use the **imperative mood** (e.g., "Fix crash in geometry kernel", not
-  "Fixed crash" or "Fixes crash").
-- A commit message can be a single line if the purpose is obvious from the
-  subject alone.
-- Otherwise, add a blank line after the subject followed by a short explanation
-  of a few lines in the body.
-
-## Code Style
-
-### Python
-
-- **Line length**: 120 characters
-- **Formatter**: black
-- **Linter**: ruff
-- Configuration is in `pyproject.toml`
-
-### C++
-
-- **Standard**: C++17 minimum
-- **Formatter**: clang-format (configuration in `.clang-format`)
-- **Linter**: clang-tidy (configuration in `.clang-tidy`)
-
-Run linters and formatters **before submitting** your pull request. Do not rely
-on CI to catch formatting issues.
-
-## Testing
-
-- Pull requests with test coverage are **much more likely to be merged**.
-- If tests are appropriate and feasible for your change, they should be
-  included.
-- Tests are not required for every change (e.g., documentation-only changes),
-  but the expectation is that testable code changes come with tests.
-- Python tests use **pytest** and are located in `test/` or `tests/` directories
-  within each package under `src/`.
-- Run the existing test suite for the package you modified before submitting.
-
-## Architecture Quick Reference
-
-### Directory Structure
-
-- `src/ifcparse/` — C++ IFC file parsing
-- `src/ifcgeom/` — C++ geometry processing (OpenCASCADE and CGAL kernels)
-- `src/serializers/` — Output format serializers (glTF, Collada, SVG, etc.)
-- `src/ifcwrap/` — SWIG Python bindings
-- `src/ifcconvert/` — CLI conversion tool
-- `src/ifcopenshell-python/` — Python API (`ifcopenshell` package)
-- `src/bonsai/` — Blender add-on (GPL-3.0-or-later)
-- `src/ifctester/` — IDS model auditing
-- `src/ifcpatch/` — IFC file manipulation scripts
-- `src/ifcdiff/` — IFC model comparison
-- `src/ifcclash/` — Clash detection
-- `src/ifccsv/` — Schedule import/export
-
-### IFC Schema Versions
-
-The library supports IFC2x3 TC1, IFC4 Add2 TC1, IFC4x1, IFC4x2, and
-IFC4x3 Add2. Schema-specific code is compiled conditionally. Be aware of
-which schema versions your change affects.
