v1.0.31

Fixed

• Show the MCP servers and their count before a session runs. A directory with no running agent used to report no servers,
  so the sidebar's "MCP servers" count sat at 0 in a new chat, on a dormant project and after the idle reaper stopped the
  last agent. The servers are now read by a short-lived agent started for that read alone.
• Keep that list current: antechamber announces mcp.status.changed when an agent starts, stops or reports new MCP state,
  so OpenChamber re-reads instead of keeping a stale count (it treats an answer as fresh for a minute).
• Stop a sign-in from failing with "pi process disposed" when OmO answers auth-start only while auth-complete is
  already running. The agent started for the sign-in was stopped mid-command; the completion now owns it until it ends.
