test: Tier 0-2 scaffolding (shell syntax, imports, entrypoints, runner metadata) #39

	name: CI (develop)

	# Lightweight PR-time test suite that actually gates merges into develop.
	# Runs the unit tests under tests/ inside the published shapepipe container
	# — no conda bootstrap, no multi-OS matrix. Complements ci-release.yml
	# (which is a heavier conda-based suite gating main/master).

	# with the PR's checkout so tests run against the proposed code.
