Enhance Linux Wayland support and refine transcription logic

- Added instructions for Linux Wayland paste setup in README.md.
- Removed unnecessary JavaScript file and updated references in HTML files.
- Updated DefaultAIPrompt to clarify the role of the transcription tool.
- Removed overlay notifications for Linux to reduce desktop clutter.
- Implemented checks to ensure transcript integrity during refinement.
- Added tests to validate transcript preservation logic.
- Removed ydotool setup script as it is no longer needed.
