- Backend: Refactored tasks.py to directly invoke run_single_fna_pipeline.py for consistency. - Backend: Changed output format to ZIP and added auto-cleanup of intermediate files. - Backend: Fixed language parameter passing in API and tasks. - Frontend: Removed CRISPR Fusion UI elements from Submit and Monitor views. - Frontend: Implemented simulated progress bar for better UX. - Frontend: Restored One-click load button and added result file structure documentation. - Docker: Fixed critical Restarting loop by removing incorrect image directive in docker-compose.yml. - Docker: Optimized Dockerfile to correct .pixi environment path issues and prevent accidental deletion of frontend assets.
