chore: update Docker configuration and entrypoint script

- Enhanced .dockerignore to exclude additional build outputs and dependencies.
- Modified dev.mjs and start.mjs to change Docker container startup behavior, removing the --build flag to preserve volumes.
- Updated docker-compose.yml to add a new volume for persisting Claude CLI OAuth session keys.
- Introduced docker-entrypoint.sh to fix permissions on the Claude CLI config directory.
- Adjusted Dockerfile to include the entrypoint script and ensure proper user permissions.

These changes improve the Docker setup and streamline the development workflow.
