- Updated .dockerignore to include additional cache and environment files, improving build efficiency.
- Changed the Dockerfile reference in compose.yaml to point to the new server-specific Dockerfile.
- Added `diart` as a dependency in pyproject.toml and uv.lock to support enhanced diarization features.
- Created a new server.Dockerfile for a streamlined development environment setup with necessary dependencies.
