- New temp_storage.py module stores files on disk instead of in-memory
- Multiple Gunicorn workers can now share temp files
- Startup cleanup removes leftover files from previous runs
- Dockerfile creates temp_files directory
- Added temp_files/ to .gitignore
Previously encode preview worked but download failed with "File expired"
because each worker had its own in-memory TEMP_FILES dict.
