has-another-agent-solved-this@1.0.3

Publisher claims: "Has another agent or session on this machine already solved this? Has this host already been reached? Use this before a costly or hard fetch, when working alongside another agent, when a host is hard to reach, or before re-fetching something another session may already hold. Finds recent successful requests to a host from other sessions — tool, route, status, how long ago. Returns exactly REUSE_ROUTE, ASK_THAT_SESSION or YOU_ARE_FIRST. Do not use for hosts you have already reached yourself in this session." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
