feat(cursor): Add interactive setup wizard for standalone Cursor users

Phase 2 implementation: Enhanced CLI UX with guided first-run experience.

- Add `npm run cursor:setup` command for interactive wizard
- Auto-detect Claude Code installation
- Guide provider selection (Gemini recommended for free tier)
- Configure API keys interactively with settings persistence
- Auto-start worker and install hooks
- Clear instructions for next steps

This enables Cursor users without Claude Code to easily configure
claude-mem with free-tier providers like Gemini.
