v4.0 Rust tray helper

Summary

• Rebuilt the helper as the Rust mainline Windows tray application.
• Added embedded multi-size tray/application icon and DPI-aware Windows manifest.
• Added Explorer file-copy handling so copied Windows file paths paste as WSL /mnt/... paths.
• Preserved image clipboard paste flow, async temp PNG saving, tray hotkey/mode switching, and exit cleanup.
