`monit-agent.md` ran `host.top` / `host.disk` and `monit.md` ran `host.cpu` /
`host.mem`. None of the four exist. monit-agent v0.0.7 registers exactly:
host → os.overview, os.top_processes, net.tcp_ping, http.get, shell.exec;
mysql → mysql.overview, mysql.lock_contention, mysql.query.

An agent copying these gets `unknown_tool`, and the `host.top` example also
passed `limit`, which is not a parameter of anything (`os.top_processes` takes
`top_n` / `sort_by`, and the agent validates with `additionalProperties:false`,
so a wrong key is a hard `invalid_args`, not a silent no-op).

The generated help in this repo (zz_generated_diagnostics.go,
zz_generated_response_help.go) was already correct — only these hand-written
cards drifted, because nothing checks their JSON bodies against the registry.

Replacements verified live against a real dev target. Deliberately kept
separate from the SDK-bump branch so it can land without waiting on that.
