feat(goal): 4 new subcommands for issue #140 fusion (status/complete/… #54

	# Purpose: spec-ci workflow — runs `sin spec check --all` on every PR
	# and push to main. A must-priority failure blocks the PR.
	# Docs: docs/SPEC-LAYER.md §"CI gate"
	# n8n-delegated per mandate M1 (see AGENTS.md §M1).

	# Use the existing concurrency group; spec-ci is fast (<30s) so
	# cancel-in-progress is fine.
