Merge pull request #3 from LessUp/fix/bugs-and-architecture-improvements #58

	# Continuous Integration
	# Validates code formatting, CUDA compilation, and CPU-only test execution
	#
	# Workflow separation:
	# - This workflow: formatting + CUDA compile-time checks + CPU tests (no GPU runtime)
	# - pages.yml: docs tests/build and GitHub Pages buildability
