v1.4.39

Fixed

• A terminal Cursor error after a Pi tool call no longer drops the latest checkpoint. The mid-pause save and bridge release now run before the stream is finalized.
• Pi tools whose names clash under the mcp_pi_ prefix no longer reach the wrong tool. One name map feeds discovery, catalogs, history, policy, and dispatch.
• Exec field 28 is Cursor's Task/subagent request. It is rejected with a typed SubagentError instead of an unknown-exec throw. This provider does not spawn the subagent and does not read or log the prompt or credentials that request can carry. Fixes #42.
