ci(windows): drop paths filter (trigger reliability) + NO_COLOR runner logs

The paths filter wasn't dispatching the run on the newly-added workflow (the runner is healthy
and 'declare successfully', but received no task). Match apple.yml: trigger on every push to main
+ PRs. Also set NO_COLOR in the daemon wrapper so runner.log is plain text (the ANSI spinner
garbled it).
