nanook ctl state lists configured rules; pass the rule name or its expression text

Details

When this fires

Dispatch::fire in nanook-admin/src/dispatch.rs forwarded a POST /rules/{name}/fire request and the engine reported no such rule. Rule identifiers match against the name field first, then the raw expression text; a typo, missing reload, or a rule that lives in a different agent will all reach this branch.

What to check

• Grab the live names from nanook ctl state (the rules array, name column) and reissue with the exact string (names are case-sensitive):

nanook ctl state
nanook ctl fire hot-cpu

• If the rule is missing entirely, the agent may still be running an older config. Hot-reload after editing [[alerts]]:

nanook check && nanook ctl reload
