Why: teabot's implementer and reviewer bot users should mint ephemeral,
scoped Gitea tokens on demand instead of holding standing personal access
tokens (Gitea tokens never expire on their own). This registers and mounts
the new vault-plugin-secrets-gitea engine and declares its roles, mirroring
the rancher engine wiring.
Change:
- Register the plugin in the catalog (config/plugins/vault-plugin-secrets-gitea.yaml)
pinned to the released v0.1.0 binary sha256.
- Add gitea_secret_backend + gitea_secret_backend_role modules and wire them
through config.hcl, terragrunt.hcl, and vault_cluster variables/main, using
the giteavaultsecret provider (terraform-unkin registry, v0.1.0).
- Mount the engine at gitea/ against https://git.unkin.net; seeded site-admin
credentials are read from KV (service/vault/au/syd1/secret_backend/gitea/config).
- Add teabot-implementer (write:repository, write:issue) and teabot-reviewer
(read:repository, write:issue) roles, ttl 1h / max_ttl 4h.
