fix: configure Docker to use mounted volume for basic-memory data

- Add docker-init.sh script to initialize config.json pointing to /app/data
- Update Dockerfile to use initialization script as entrypoint  
- Update docker-compose.yml comments to reflect automatic configuration
- Ensures mounted knowledge files in /app/data are properly indexed

Fixes issue where .basic-memory/config.json wasn't configured to use 
the mounted directory, causing files in /app/data to not get indexed.
