fix: address review feedback — pin dependency and add sessionCodec

- Pin @nousresearch/paperclip-adapter-hermes to v0.1.0 tag for
  reproducible builds and supply-chain safety
- Import and wire hermesSessionCodec into the adapter registration
  for structured session parameter validation (matching claude_local,
  codex_local, and other adapters that support session persistence)
