The `gt plugin run` command was recording a "success" run even though it
only prints plugin instructions for an agent/user to execute - it doesn't
actually run the plugin.
This poisoned the cooldown gate: CountRunsSince counted these false
successes, preventing actual executions from running because the gate
appeared to have recent successful runs.
Remove the recording from `gt plugin run`. The actual plugin execution
(by whatever follows the printed instructions) should record the result.
