Plugin Stuff #37

	name: Stack Matrix

	# Runs the full 13-stack generate → install → lint → typecheck → pytest
	# pipeline. This is the slow tier — gated off the default ``ci.yml`` run so
	# day-to-day PRs stay fast, but it fires on any PR touching template or
	# core-engine code (where drift lands) and nightly to catch anything that
	# merged without touching a gated path.

	pull_request:
	branches: [ main ]
	paths:
	- 'aegis/templates/**'
