fix: pin playwright-go in browser-test scaffold (Starter Templates CI) #3

	name: API Baseline

	# F3 merge gate: the public-API baseline tests run on every PR (and push to main), so an
	# accidental breaking change to an exported surface fails BEFORE merge — not only at release
	# tag time. This makes the major/minor boundary (VERSIONING.md) mechanically enforced: a removed
	# or changed baseline line fails the gate; an intentional change regenerates the baseline
	# (UPDATE_API_BASELINE=1 go test ./<pkg>/) as a reviewed commit.
