chore(mcp): clean bridge build caches

 This installs local Git hooks, checks required tools, generates `.env`, and verifies a full TrapOS install on a fresh CraftOS-PC state.
 
+## Cleaning
+
+- `just clean` — clears the `mcp-bridge` build caches (`node_modules/.cache/tsc`, `node_modules/.cache/eslint`). Safe to run anytime; `just reinstall` chains it with `just install`.
+- `just clean-env` — deletes `.env`. Run only when you actually want to drop locally generated tokens.
+
 See [`docs/README.md`](docs/README.md) for repository docs and [`docs/adrs/README.md`](docs/adrs/README.md) for architecture decisions.
