Run TS Cleanup

A TypeScript codebase accumulates. Features get deprecated but their files stay. A refactor lands half-finished and both abstractions survive. An LLM writes cn for the fourth time in a fourth directory. Dependencies outlive the code that imported them. Types get exported "just in case" and never consumed. This skill sweeps all of it into a clean end state:

• Every dead symbol, file, export, type, and dependency is found by a real engine, not by guesswork — and each finding is triaged before deletion, never deleted on the engine's word alone.
• Every deletion lands in a reversible wave behind a passing verification gate, so any single step reverts with one git revert.
• The root cause is addressed, not just the symptom: duplicate helpers get consolidated, circular barrels get untangled, single-use wrappers get inlined — so the same bloat does not regrow.
• The codebase ends more navigable than it started, for the next agent and the next human, without a single behavioural change.

This is a finishing tool. Run it on a green main branch, not mid-feature.
