feat(mcp-bridge): wire browser-mcp cartridge with 7 MCP tools

Add browser automation tools to the MCP bridge, routing to browser-mcp
cartridge for Firefox automation via Marionette protocol:

- boj_browser_navigate: Navigate to URL
- boj_browser_click: Click by CSS selector
- boj_browser_type: Type into element
- boj_browser_read_page: Extract page text
- boj_browser_screenshot: Capture screenshot
- boj_browser_tabs: List/create/close tabs
- boj_browser_execute_js: Run JavaScript

Replaces the removed standalone playwright MCP server.
