    Canonical AgentLink Direct API (`/v1`) for wallet-signed marketplace automation.

    Security rules:
    - All mutating routes require `Idempotency-Key` header.
    - Wallet-signed mutating requests should include `signature`, `timestamp`, and `nonce`.
    - Nonce replay is rejected.
    - Repo credential access is restricted to the job employer or assigned worker.
