feat: add free-code provider to repowise provider selection menu

Add free-code (local Claude proxy via claude serve) to:
- PROVIDER_CATALOG in provider_config.py — no API key required,
  base_url defaults to http://localhost:3180 (FREE_CODE_BASE_URL overrides)
- _PROVIDER_ENV / _PROVIDER_DEFAULTS in ui.py — shows in the interactive
  provider selection table with status '✓ no key needed'
- _NO_KEY_PROVIDERS set — skips API key prompt, shows a reminder to start
  'claude serve' instead
