feat: improve install.sh UX with clearer prompts and correct tap syntax

- Add explicit password prompt warning for Xcode CLT installation
- Change to 'brew install openbootdotdev/tap/openboot' (full tap path)
- Remove redundant tap check since full path auto-taps if needed
- Improve dry-run output to show actual command that will run
- Use consistent ✓ checkmark for success messages

User experience improvements:
- Users now know upfront that Xcode CLT requires password
- 'Press Enter to launch installer' gives users control
- Clearer indication of what's happening during installation
