feat: add custom Dockerfile with Hermes adapter baked in

Creates ai/paperclip/ with:
- Dockerfile: extends upstream paperclip image, pre-installs
  hermes-paperclip-adapter@0.3.0 npm package as seed data
- docker-entrypoint.sh: seeds the adapter plugin on first boot
  if the persistent volume is empty, then runs original startup

This ensures the Hermes adapter is available on first boot without
requiring network access — no npm install needed at runtime. The
adapter persists on the Docker volume across restarts.
