feat: add function to check if Claude is running before prompting for…

… restart

- Implemented `isClaudeRunning` function to determine if the Claude application is active on Windows, macOS, or Linux.
- Integrated this check into the `promptForRestart` function to enhance user experience by preventing unnecessary prompts when Claude is not running.

Fixes #21
