feat: add skills via tanstack intent #3

	# check-skills.yml
	#
	# Validates @tanstack/intent skills on PRs that touch skills or artifacts.
	#
	# Staleness checking after a release is intentionally NOT automated here — run
	# `pnpm test:intent` (which calls `intent validate && intent stale`) locally
	# before cutting a release. Keeping this workflow validation-only means it
	# needs zero write permissions.
