Implement a generic Vault/OpenBao secrets engine that issues short-lived signed JWTs for self-made services, replacing per-app static bearer Secrets. Per-app roles set the audience, TTLs, subject allowlist and custom claims; creds/<role> mints an EdDSA (or RS256) token. Apps validate offline against the unauthenticated JWKS + OIDC-metadata paths, so there is no Vault round-trip per request. Signing keys are seal-wrapped in the barrier and rotate with a configurable JWKS grace window. Mirrors the other vault-plugin-secrets-* engines: cmd ServeMultiplex, Makefile with patch|minor|major tags, .woodpecker CI (k8s resources + SA), dual-flavour nfpm RPM to artifactapi rpm-internal. Tests (-race) cover issuance+JWKS validation for both algorithms, rotation grace/trim, role isolation, subject allowlist and the unauthenticated/seal-wrap wiring.
