Sovereign Pinner CID Calculator and Pinning (v3)

This tool deterministically computes IPFS Content IDs (CIDs) for provided content and, when requested, arranges pinning to decentralized storage providers such as IPFS or Arweave. It accepts content (raw text or base64-encoded binary), encoding (utf-8 or base64), mode (calculate or pin), optional filename, and optional pinning_service_key used when mode is pin. At runtime the worker combines these inputs with any execution payloads, such as gateway or pinning responses, and must return a JSON object that strictly validates against the system-provided structured output schema (auto-produced, not supplied here), with correct types, enums, and no extra fields.
