Subject: [PATCH] feat: add Cloudflare bypass to fetchSourceFurnidata using
 puppeteer

- Add cf-fetch.ts with puppeteer-extra + stealth plugin for CF bypass
- Modify fetchSourceFurnidata to detect CF challenge and retry with puppeteer
- Restore Leet, Hubbly, and Habblet City to clone sources (now CF-protected)
