Subject: test(gpu): Add comprehensive TextureManager tests

Created automated test suite for texture_manager.cc with 7 test cases:
- Basic initialization and shutdown
- Create texture from raw RGBA8 data
- Create procedural texture (using gen_noise)
- Get texture view for non-existent texture (nullptr test)
- Create and retrieve multiple textures
- Procedural generation failure handling
- Shutdown cleanup verification

Replaced old compilation-only test with proper automated test using
WebGPUTestFixture for headless GPU testing. Registered with CTest as
test #27 (TextureManagerTest).

Coverage Impact:
- Before: texture_manager.cc had 0% coverage (not run by CTest)
- After: 100% coverage (64/64 lines, 5/5 functions)

All 27 tests pass.
