Controls the watcher daemon, Fleet's autonomous engine. It runs three loops: a label watcher that polls GitHub for label changes (about every two minutes) and publishes fabric events, a subscription processor that matches new events to agent subscriptions (about every ten seconds) and starts agents, and an agent scheduler that fires cron-scheduled agents.
fleet watcher start launches the daemon for the current repo (license-gated). Pass --org <name> for an org-level watcher across all repos in that org. The watcher does not respawn crashed agents; work is re-dispatched via the reactive chain.
