Subject: refactor: Reorganize tests into subsystem subdirectories

Restructured test suite for better organization and targeted testing:

**Structure:**
- src/tests/audio/    - 15 audio system tests
- src/tests/gpu/      - 12 GPU/shader tests
- src/tests/3d/       - 6 3D rendering tests
- src/tests/assets/   - 2 asset system tests
- src/tests/util/     - 3 utility tests
- src/tests/common/   - 3 shared test helpers
- src/tests/scripts/  - 2 bash test scripts (moved conceptually, not physically)

**CMake changes:**
- Updated add_demo_test macro to accept LABEL parameter
- Applied CTest labels to all 36 tests for subsystem filtering
- Updated all test file paths in CMakeLists.txt
- Fixed common helper paths (webgpu_test_fixture, etc.)
- Added custom targets for subsystem testing:
  - run_audio_tests, run_gpu_tests, run_3d_tests
  - run_assets_tests, run_util_tests, run_all_tests

**Include path updates:**
- Fixed relative includes in GPU tests to reference ../common/

**Documentation:**
- Updated doc/HOWTO.md with subsystem test commands
- Updated doc/CONTRIBUTING.md with new test organization
- Updated scripts/check_all.sh to reflect new structure

**Verification:**
- All 36 tests passing (100%)
- ctest -L <subsystem> filters work correctly
- make run_<subsystem>_tests targets functional
- scripts/check_all.sh passes

Backward compatible: make test and ctest continue to work unchanged.

handoff(Gemini): Test reorganization complete. 36/36 tests passing.
