	# Performance Testing Workflow
	#
	# This workflow runs performance benchmarks to ensure the library remains fast and efficient.
	# It runs on every push/PR to main/master and can be triggered manually.
	#
	# What it measures:
	# 1. wcwidth function performance - how fast single character width calculation is
	# 2. wcswidth function performance - how fast string width calculation is
	# 3. Memory usage under load - ensures no memory leaks
	# 4. Bundle size - tracks if the package is getting larger
	# 5. Performance regression detection - compares against baselines
	#
	# This helps catch performance issues early and ensures the library stays performant.
