fix: clean up logging colors, reduce noise, enable Tailscale access (#166)

* fix: reserve red for real errors, reduce log noise, allow Tailscale access

- Add _ColorFormatter: red = ERROR/CRITICAL only, yellow = WARNING, green = INFO
- Override uvicorn's default colors to use our scheme
- Downgrade discord "not installed" from ERROR to WARNING (optional dep)
- Downgrade DuckDuckGo unavailable from INFO to DEBUG
- Stop discord token watcher retry loop when discord.py not installed
- Add configurable trusted_hosts setting; dev mode allows all hosts
- Exclude .claude/ from uvicorn reload watcher (worktree isolation)
- Fix pre-commit hook: use tox -e unit, bump timeout to 60s

* fix: pre-commit hook auto-formats with black+isort before testing

Formatting should never block a commit — just fix it automatically.
