REPO_POLICIES.md asks for the standard .gitignore and .editorconfig
followed by the repository's own entries, and for the canonical
.golangci.yml. The shared parts and .golangci.yml now match the
sneak/prompts copies at 065357920a0a09bd736bf33d4cb5ce935fdc2328 byte
for byte. .editorconfig has no entries of its own left, since the
standard file now carries the [*.go] section. .golangci.yml disables
canonicalheader, as the canonical copy does.
