Add ignore patterns for large binary files to prevent virtual memory … - #2761

Uses a 2x2 matrix approach: Binary vs Text × Large vs Small

BINARY FILES (always ignored):
- Executables: exe, dll, so, dylib, app, dmg, pkg, msi, deb, rpm
- Compiled: jar, war, ear, class, o, a, pyc, pyo, wasm
- Images: jpg, jpeg, png, gif, bmp, tiff, webp, ico
- Media: mp4, avi, mkv, mov, mp3, wav, flac, pdf
- Cache directories: __pycache__, .cache, .pytest_cache, .tox

TEXT FILES (size-filtered):
- Small files (< 1MB): Included in project tree
- Large files (≥ 1MB): Excluded via ripgrep --max-filesize

This approach:
- Preserves small archives (test fixtures, config backups)
- Handles large text files (logs, data dumps)
- Eliminates virtual memory allocation during startup
- Provides precise filtering without performance overhead

Fixes startup memory consumption with large .tar.gz files while
maintaining access to legitimate small binary files.
