feat: add browser automation tool using Vercel agent-browser

- Add src/tools/browser.rs with BrowserTool implementation
- Wraps agent-browser CLI for AI-optimized web browsing
- Supports: open, snapshot, click, fill, type, screenshot, wait, etc.
- Uses refs (@e1, @e2) from accessibility snapshots for precise element selection
- JSON output mode for LLM integration
- Security: allowlist-only domains, blocks private/local hosts
- Add session_name to BrowserConfig for persistent sessions
- Register BrowserTool in tools/mod.rs alongside BrowserOpenTool

All tests pass.
