ci: add quick cross-platform test workflow (ubuntu + windows, py3.12) #1

	name: CI

	# Quick test CI: runs the stdlib-unittest suite on both supported platforms
	# (Windows + Linux is a load-bearing requirement — see CLAUDE.md). The suite is
	# pure logic (text cleanup, loop collapse, batch accounting) and needs neither
	# Tesseract nor a running Ollama, so it stays fast.
