v0.4.2

Fixed

• Browser bridge re-election (macOS). A server that started while another instance owned bridge.sock attached to it as an RPC client and stayed an orphan after that owner exited: nothing re-bound the socket, Chrome's native host could not connect, and every browser_* tool reported the extension as disconnected until the server was restarted. The bridge now re-runs the owner election when the RPC link drops and before each call while unowned. (#5)
• Bridge retry (Linux/Windows). The Rust host gave up on the browser bridge for good when another server owned it at startup; it now retries every two seconds in the background and takes over once that owner exits.

Notes

• No tool changes (30 tools). Chrome extension unchanged (0.4.0).
• If the "MT Code Desktop Control" extension is missing from chrome://extensions after an app update, load it unpacked again from chrome-extension/; the manifest key keeps the extension id stable from any path.
