Add component-level targeting to start, stop, and restart

Browse Source 
Allow start/stop/restart to target a single component via
<service>/<component> syntax, matching deploy/logs/purge. When a
component is specified, start/stop skip toggling the service-level
active flag. Agent-side filtering returns NotFound for unknown
components.
