Cleanup GHCR Images #14

	# Cleanup GHCR Images
	#
	# This workflow cleans up old images from GitHub Container Registry
	# to prevent unlimited storage growth. It runs weekly and removes:
	# 1. Old test-runner versions (keeps 5 most recent)
	#
	# Note: cleanup of dated vector nightly images requires a token with
	# delete:packages scope (GITHUB_TOKEN is insufficient for org-owned
	# container packages). This is tracked separately.
