✨ feat: add interactive setup prompt with lipgloss styling and emojis

Add styled first-time setup UI using lipgloss with Tokyo Night theme
colors. The prompt now includes emojis and better visual feedback when
creating the initial configuration file.

- Add new ui module with styled render functions
- Prompt user for project paths interactively on first run
- Parse comma-separated paths with whitespace trimming
- Show styled success message with configured directories
- Add lipgloss dependency for terminal styling
