/**
 * `wicked-crew mcp` — stdio MCP server that proxies the wicked-crew daemon's
 * run-lifecycle surface. One tool per verb; all calls are 1:1 HTTP passthroughs
 * to a running daemon. The MCP server is stateless: it carries NO in-process
 * adapter and does NOT open the engine DB.
 *
 * Usage:
 *   wicked-crew mcp [--port <n>]   # connects to daemon at 127.0.0.1:<port>
 *
 * The daemon must already be running (`wicked-crew serve`). Governance semantics,
 * repo-scoping, and run authority all live in the daemon — no new authority here.
