docs: defer full STL removal to Phase 2

Lowered the priority of the 'replace STL' task. It will be addressed in the final optimization phase (Phase 2) to simplify current development. Hot paths in AssetManager and Procedural remain optimized.

handoff(Gemini): STL usage is now permitted for non-critical paths until the final optimization phase. PROJECT_CONTEXT.md and TODO.md updated accordingly.

 ## Project Roadmap
 
 ### Recently Completed
-- **Task #20: Platform & Code Hygiene**: Consolidated platform-specific shims and WebGPU headers into `platform.h`. Refactored `platform_init` and `platform_poll` for better abstraction. Removed STL containers (`std::map`, `std::vector`, `std::string`) from `AssetManager` and procedural generators.
+- **Task #20: Platform & Code Hygiene**: Consolidated platform-specific shims and WebGPU headers into `platform.h`. Refactored `platform_init` and `platform_poll` for better abstraction. Removed STL containers from initial hot paths (`AssetManager`, `procedural`). Full STL removal for CRT replacement is deferred to the final optimization phase.
 - **Task #26: Shader Asset Testing & Validation**: Developed comprehensive tests for `ShaderComposer` and WGSL asset loading/composition. Added a shader validation test to ensure production assets are valid.
 - **Asset Pipeline Improvement**: Created a robust `gen_spectrograms.sh` script to automate the conversion of `.wav` and `.aif` files to `.spec` format, replacing the old, fragile script. Added 13 new drum and bass samples to the project.
 - **Build System Consolidation (Task #25)**: Modularized the build by creating subsystem libraries (audio, gpu, 3d, util, procedural) and implemented helper macros to reduce boilerplate in `CMakeLists.txt`. This improves build maintenance and prepares for future CRT replacement.
