fix: Claude usage parsing for CLI v2.x and trust prompt handling

- Use node-pty on all platforms instead of expect on macOS for more reliable PTY handling
- Use process.cwd() as working directory (project dir is likely already trusted)
- Add detection for new trust prompt text variants ("Ready to code here", "permission to work")
- Add specific error handling for trust prompt pending state
- Show helpful UI message when trust prompt needs manual approval
