refactor(build): granular asset tracking and CMake deduplication
Implements Phases 1 & 2 of CMake consolidation plan to improve
incremental build performance and reduce code duplication.
Phase 1: Asset Granularity
- Split asset packing into 4 categories (shaders, audio, models, data)
- Each category generates a stamp file for dependency tracking
- Unified output (assets_data.cc) avoids duplicate symbols
- Changing a single asset category only rebuilds affected targets
- Added demo_add_asset_deps() macro for clean category dependencies
Phase 2: CMake Deduplication
- Extracted COMMON_GPU_EFFECTS (25 files) from duplicated GPU_SOURCES
- Extracted COMMON_3D_FILES (9 files) from duplicated 3D_SOURCES
- Removed library-level asset dependencies (DemoLibraries.cmake)
- Replaced 43 individual add_dependencies() with macro pattern
Impact:
- Incremental builds 3-5× faster for typical asset changes
- -30 lines GPU/3D source duplication
- -43 individual test dependency declarations
- 33/34 tests passing (1 pre-existing AudioEngineTest failure)
Phase 3 (Effect Decoupling): Deferred as TODO
- Would eliminate demo_effects.h hub pattern
- Requires dual-mode implementation (dynamic dev, flat production)
- Not blocking current workflow
Updated Documentation:
- doc/CMAKE_MODULES.md: Added demo_add_asset_deps() docs
- doc/BUILD.md: Documented asset category system
