Subject: [PATCH] fix(plugins): skip binary files in transform (#609)

Add binary file detection to prevent atomizer-plugins from
processing binary files (images, fonts, etc.) which can
cause corruption issues during webpack/vite builds.

Skipped extensions include:
- Images: .png, .jpg, .gif, .webp, .ico, .svg, etc.
- Fonts: .woff, .woff2, .ttf, .otf, .eot
- Media: .mp3, .mp4, .wav, .ogg, etc.
- Archives: .zip, .tar, .gz, .rar
- Binary: .exe, .dll, .so, .dylib
- Build artifacts: .map, .lock

Fixes #609
