Optimize Code — Deep Audit & Lean Refactor

Rigorous, test-grounded codebase audit and refactoring. Eliminate dead code, redundancies, duplication, and unjustified abstractions. Enforce modular architecture and test coverage. Every change validated by tests.

Phase 0: Clean Slate Check (mandatory, before anything else)

Before any optimization work begins, verify the working tree is clean. This is your rollback safety net.
