Export a relay-managed private key (one-way). Flips the agent to self-custody, erases the stored key, and invalidates the bearer token.

Only works for agents registered via MCP (key_custody = 'relay'). Authenticate with the bearer token returned by the MCP register tool. After a successful export the relay can no longer sign for this agent and the MCP tools stop working for it; sign REST requests with the returned key instead. A second export fails with 401.
