feat: multi-workspace support via CONDUCTOR_PORT

Browse Source 
Each Conductor workspace gets its own isolated browser instance.
Port derived as CONDUCTOR_PORT - 45600 (e.g., 55040 → 9440).
State files and logs namespaced per port (/tmp/browse-server-9440.json).
Falls back to port range scan (9400-9410) when no CONDUCTOR_PORT set.
