Squash Benchmark Branches #59

	name: Squash Benchmark Branches

	# The continuousbenchmark and continuousbenchmark_net80 branches accumulate
	# commits from the benchmark-action/github-action-benchmark action (one per
	# benchmark run). Each commit rewrites a ~37 MiB data.js file, which bloats
	# the repository pack file and slows git clone. This workflow periodically
	# squashes each branch to a single orphan commit, keeping only the latest
	# file contents.
