fix: use npm package instead of GitHub URL dependency

- Published hermes-paperclip-adapter@0.1.0 to npm registry
- Replaced github:NousResearch/hermes-paperclip-adapter with
  hermes-paperclip-adapter ^0.1.0 (proper semver, reproducible builds)
- Updated imports from @nousresearch/paperclip-adapter-hermes to
  hermes-paperclip-adapter
- Wired in hermesSessionCodec for structured session validation

Addresses both review items from greptile-apps:
1. Unpinned GitHub dependency → now a proper npm package with semver
2. Missing sessionCodec → now imported and registered
