Fix hanging install: remove Claude Code CLI check

- Removed npx @anthropic-ai/claude-code --version check during install
- This was causing the install script to hang due to network/auth delays
- Claude Code will be downloaded automatically when first used by Ralph
- Installation should now complete quickly without hanging
