refactor(#2455): split hive-agent-mcp into its own bin crate

hive-ag3nt/src/bin/hive-agent-mcp.rs

-//! MCP-server binary for the built-in hyperhive surface. Runs a long-lived
-//! streamable-http listener (the `hive-mcp-http` systemd unit) on `--http
-//! <addr>`; tools dispatch through `/run/hive/mcp.sock` back into the
-//! hyperhive broker. claude reconnects to the stable URL each turn via
-//! `--mcp-config`, avoiding the per-turn re-registration race. HTTP is the
-//! sole transport — there is no stdio mode. Sibling of `hive-agent` (the
-//! serve loop that renders the `--mcp-config` blob pointing here) and
-//! `hive-agent-wake`.
