chore: update version and enhance installer configuration

- Bump application version from 0.0.1 to 0.1.0.
- Exclude Linux runtimes from the installer files.
- Update icon names for consistency in the installer script.
- Improve logging in MainWindow and NotepadWindow for better AI error handling.
- Adjust AI manager initialization to handle exceptions gracefully.
- Update README to reflect new AI features and installation instructions.
