install-smoke #5

	name: install-smoke

	# Installs precise FROM PyPI on a clean runner (no source checkout shadowing the import) and
	# exercises the published wheel. Three triggers:
	# * workflow_dispatch — on demand (override the install spec, e.g. precise==1.0.0rc1)
	# * schedule — weekly drift canary: does `pip install precise` still work today?
	# * workflow_run — right after a successful deploy (validates each release)
	# Note: schedule/workflow_run only fire once this file is on the default branch.
