Zach Kelling 961c42e204 feat: add FHE example apps for all Pars PIPs
- data-seal: Verifiable Data Integrity Seal (PIP-0010/LP-0535)
  FHE-encrypted tamper-proof sealing with Public/ZK/Private modes,
  batch sealing, homomorphic verification

- content-provenance: AI & Media Content Provenance (PIP-0011/LP-7110)
  Model manifests, output attestation via homomorphic comparison,
  media derivation DAGs

- encrypted-crdt: Encrypted CRDT (PIP-0013/LP-6500)
  LWW-Register with FHE values, OR-Set with tag-based add/remove,
  Lamport timestamp conflict resolution, deterministic merge

- shadow-governance: Shadow Government Protocol (PIP-7010)
  Anonymous ministries, encrypted voting with homomorphic tallying,
  nullifier-based anti-fraud, quorum enforcement

Each example includes Solidity contracts, Hardhat tests, CLI tasks,
and README linking to corresponding PIP and LP specifications.
