Execute an internal Patina Unity command. Targets the agent working-directory workspace by default; pass workspace to target a different project, or sessionId (from patina_sessions) to target one editor directly.

Browse Patina's Unity command catalog without loading every command schema. Filter by category/search/command; set include_schema=true only for commands you intend to call.

Return Patina server version, compact MCP surface status, bridge port, command count, and a broker summary (agentClientCount, unitySessionCount counting both connected and reloading sessions, reloadingSessionCount, and per-session detail). Pass include_unity_state=true to prove the routed Unity session is actually responding, not just registered.

List active Unity sessions registered with the shared Patina broker, including workspace paths, health, state (connected|reloading|stale), and reloadCount. Check state="reloading" before assuming a failed call means Unity disconnected -- it may just be recompiling.
