verify

Run the checks that have to pass before a FreeReps commit lands — Go build, vet, tests and golangci-lint, the frontend type check and build, and the document contract check. Triggers — "verify", "prüf das durch", "vor dem commit", "läuft das durch", "check before committing", "run the checks", "does CI pass". Not for running the server itself — that is server/CLAUDE.md.
