Parse generated AAS 1.08 face settings

[themuffinator]

Summary

• accept the AAS 1.08 generateAllFaces setting already emitted by openQ4's writer
• initialize both Quake 4 builder flags deterministically and preserve their actual values when writing
• add a focused parser/writer contract to local and CI validation
• document the player/mod-author-visible warning fix

Fixes #137.

Investigation

The archive supplied in #123 (SHA-256 CED6E9D92E67D8FF71E1F2E93B68D7F6DD7C961D7E759E90E3AA243408AED187) contains .aas32, .aas48, .aas96, .aas128, and .aas250 files that all carry generateAllFaces = 0. openQ4's writer emits that key, but idAASSettings::FromParser handled only the neighboring generateTacticalFeatures key. This produced three warnings per file while leaving the face flag uninitialized.

Validation

• python tools/tests/aas_settings_contract.py
• python tools/tests/docs_link_integrity.py
• python tools/tests/release_tooling_safety.py
• tools/build/meson_setup.ps1 compile -C builddir (Windows x64 client, dedicated, SP, MP, OpenGL, Vulkan)
• git diff --check
• current 1280x720 windowed OpenGL run using the archive's exact .map, .proc, .cm, and five AAS files from an isolated loose path
  • all five AAS files opened from that path and gameplay initialized
  • no generateAllFaces/invalid-token, stale-AAS, navigation-load, engine error, or fatal diagnostic
  • engine TGA SHA-256: E62BD7DE995E16D31890CE9E44625FB829B20541DD7B7CB31729251214548F38

Final validation is complete:

• The reporter-supplied airdefense1 fixture loaded all five generated AAS variants (aas32, aas48, aas96, aas128, and aas250) with no parse, stale-file, or load errors.
• Gameplay initialized on the exact supplied map in a windowed OpenGL run.
• Engine log SHA-256: 74E5C6775C75CEA391E9E6D9E16443A026EFFAFDAC9291072F2966F50A73B196
• Engine-render-target screenshot SHA-256: E62BD7DE995E16D31890CE9E44625FB829B20541DD7B7CB31729251214548F38
• The complete commit-validation matrix passed: Windows x64, Linux x64/ARM64 GCC and Clang variants, ASan+UBSan, macOS ARM64/Intel OpenGL and Metal, both universal2 assemblies, validation smoke, and the ARM64 cross-build.

The four push-workflow macOS smoke failures are the already-documented hosted-runner OpenGL 2 compatibility limitation inherited unchanged from main; the corresponding commit-validation builds and package assemblies all pass.
