fix: update setup/config UI for local browser mode

- tools_config.py: Add 'Local Browser' as first provider option
  (no API keys needed, same npm install for agent-browser)
- setup.py: Show 'Browser Automation (local)' when agent-browser
  CLI is found but no Browserbase key is set
- config.py: Mark BROWSERBASE_* descriptions as optional
- status.py: Note that local browser works without Browserbase
