feat(metrics)!: default metrics.require_auth to true #388

	# Fast lane — gates every PR (ADR 0009 §"CI integration (PR-gate vs scheduled)").
	# Runs the bounded, deterministic subset: build, `go test -race`, lint, the
	# Tier-1 fuzz seed corpora (executed as ordinary `go test`), and — once they
	# land — the deterministic Tier-2 invariants. Unbounded generative fuzz and the
	# long sim / Tier-3 interop runs live in the scheduled slow lane
	# (.github/workflows/scheduled.yml), never here.
