fix(macos): Handle @rpath references in dylib bundling script

[dodidev]

Summary

Fix macOS runtime crash caused by missing transitive @rpath dependencies.

The copy-macos-dylib.sh script previously only copied dynamic libraries with absolute Homebrew paths. This caused runtime crashes (e.g., dyld: library not loaded) because it missed transitive dependencies that rely on relative @rpath references—such as libwebp.7.dylib failing to load libsharpyuv.0.dylib.

This PR enhances the dependency resolution inside scripts/copy-macos-dylib.sh to recursively discover, copy, and link both absolute and @rpath Homebrew libraries.

Key Changes

• Dynamic @rpath Extraction: Uses otool -L to scan binaries and discover all nested @rpath dependencies.
• Recursive Dependency Resolution: Locates the missing @rpath libraries within Homebrew, copies them to the app bundle, and updates their install names.
• Error Prevention: Emits clear warnings if an @rpath library cannot be found in the expected Homebrew path to simplify troubleshooting.
