* refactor(palette): remove unused backward-compat aliases and add module docs
- Remove DEEPSEEK_AQUA_RGB, DEEPSEEK_NAVY_RGB, DEEPSEEK_AQUA, DEEPSEEK_NAVY
(unused backward-compatible aliases with no references in production code)
- Add module-level doc comment explaining the three-layer palette organization:
RGB tuples, semantic Color constants, and backward-compat aliases
- Note that some constants are kept for design-system completeness
* fix: remove deprecated color audit test (DEEPSEEK_AQUA no longer exists)
* fix: remove unused import in palette_audit test
