fix: remove large binary files from git tracking and improve .gitignore

- Remove large binary files (apt-ostree, apt-ostreed) from debian/ directory
- Add comprehensive patterns for debug symbols and large binary files
- Add patterns for additional build artifacts and large file types
- Prevent future commits of large files that should be ignored
- This should significantly reduce repository size
