launchctl kickstart returns exit code 113 ("Could not find service") when
the plist exists but the job hasn't been bootstrapped into the runtime domain.
The existing recovery path only caught exit code 3 ("unloaded"), causing an
unhandled CalledProcessError.
Exit code 113 means the same thing practically -- the service definition needs
bootstrapping before it can be kicked. Add it to the same recovery path that
already handles exit 3, matching the existing pattern in launchd_stop().
Follow-up: add a unit test covering the 113 recovery path.
