NIGHTGATE v0.3.0

@odatano/nightgate 0.3.0

0.3.0 adds a full transaction-submission layer on top, so the plugin now both reads Midnight
chain data and writes to it via Compact contracts and wallet operations.

Highlights

• Contract submission: deployContract / submitContractCall with
  build → sign → submit through the Midnight JS SDK, run in a worker thread.
• Async job model: long-running actions return { jobId, status }
  immediately; poll getJobStatus(jobId, sessionId). Crash-recoverable.
• Wallet & funds: connectWalletForSigning (BIP39, Lace-compatible HD
  derivation), sendNight, shieldFunds / unshieldFunds, DUST
  register/deregister, plus read-only balance & fee-estimate diagnostics.
• Tiered disclosure: AttestationVault contract +
  Attestations / DisclosureRoles, the AttestationService SDK mixin
  (public / legitimate_interest / authority tiers), and anchorDocument
  / verifyDocument for on-chain document anchoring (caller-managed storage).
• ZK predicate attestations: prove value ≤ / ≥ threshold over a hidden
  value without revealing it (issuePredicateAttestation /
  verifyPredicateAttestation);
• Production private state: CAP-DB-backed, AES-256-GCM encrypted provider
  replacing the SDK's LevelDB store.
• Four OData V4 services: Nightgate, Indexer, Analytics, Admin.

Notes

Verified live on preprod: contract deploy + call, and a ZK predicate proof (47300 ≤ 50000 accepted, 51 ≤ 50 rejected by the circuit).
