Add ignore patterns for large binary files to prevent virtual memory …

[zelenkovsky]

Try to exclude potentially large binary files to avoid memory overcommitement issue (https://github.com/sst/opencode/issues/2585)

• Added archive files: tar.gz, tgz, tar, zip, 7z, rar, bz2, xz, gz, lz4, zst
• Added database files: db, sqlite, sqlite3
• Added binary executables: exe, dll, so, dylib, app, dmg, pkg, msi, deb, rpm
• Added compiled artifacts: jar, war, ear, class, o, a, pyc, pyo
• Added media files: mp4, avi, mkv, mov, mp3, wav, flac, pdf
• Added cache directories: pycache, .cache, cache, .pytest_cache, .tox

This resolves high virtual memory consumption during startup when large archive files are present in the working directory.
