v4.0.0: adopt /v4 module path + release-guard fix #7

	name: Doc Samples

	# F1 type-level gate: every `gwc:build`-marked complete-file Go sample in the docs is COMPILED
	# against the real module (written to a throwaway module with a replace → repo, then `go build`).
	# This catches the failure the parse-gate cannot — a runnable sample that still parses but uses a
	# renamed/removed API. The fast parse-gate (TestDocsHaveNoBrokenGoSamples) runs in the normal
	# `go test ./...` lane; this heavier compile gate runs here, behind the `doccompile` build tag.
