refactor(hive-ag3nt): split hive bin into hive-agent / hive-agent-mcp / hive-agent-wake

+//! MCP-server binary. Default is stdio — spawned by `claude` via
+//! `--mcp-config`; tools dispatch through `/run/hive/mcp.sock` back into
+//! the hyperhive broker. Pass `--http <addr>` to instead run a long-lived
+//! streamable-http listener (persistent daemon, the `hive-mcp-http`
+//! systemd unit) that claude reconnects to each turn, avoiding the
+//! per-turn stdio re-registration race. Sibling of `hive-agent` (the
+//! serve loop that renders the `--mcp-config` blob pointing here) and
+//! `hive-agent-wake`.
