docs: Streamline top-level project files

Move implementation details to design docs, keep TODO.md and
PROJECT_CONTEXT.md concise and high-level. Improves readability.

Changes:
- TODO.md: Condensed from 162 to 52 lines
- PROJECT_CONTEXT.md: Grouped design docs by category
- Recently Completed: Date-grouped format

-## Recently Completed (February 2026)
+**Meta:**
+- `doc/CONTEXT_MAINTENANCE.md` - Context hygiene protocol
 
-- **Hot-Reload File Watcher** (Feb 9) - Debug-only file change detection with `--hot-reload` flag. Watches config files (assets, sequences, music) and notifies on changes. 0 bytes overhead in release builds.
+---
 
-- **WGSL Uniform Buffer Validation (Task #75)** (Feb 9) - Standardized uniform buffer layout. Validation tool integrated into build. All effects use `CommonPostProcessUniforms` (binding 2) + effect-specific params (binding 3). Added `UNIFORM_BUFFER_GUIDELINES.md`.
+## Recently Completed
 
-- **Uniform Buffer Alignment (Task #74)** (Feb 9) - Fixed WGSL `vec3<f32>` alignment issues. Demo runs with 0 validation errors.
+**Feb 9, 2026:**
+- Hot-reload file watcher (debug-only, 0 bytes overhead)
+- WGSL uniform buffer validation (Task #75)
+- Uniform buffer alignment fixes (Task #74)
 
-- **Shader Parametrization (Task #73)** (Feb 8) - Full uniform parameter system with .seq syntax. FlashEffect, ChromaAberrationEffect, GaussianBlurEffect support dynamic parameters. Size: ~400-500 bytes.
+**Feb 8, 2026:**
+- Shader parametrization system (Task #73)
