- New scrapers: fibermall.ts (WooCommerce), vcelink.ts (Shopify), opticsbay.ts (WooCommerce) - QSFPTEK rewritten to use /mall/commodity/list API (old OpenCart /c/*.html paths gone 404) - New: attribute-based filtering by data rate (1G/10G/25G/40G/100G/200G/400G/800G) - Scrapes HTML fragments, extracts US$ prices and product URLs - scheduler.ts: +3 queues/schedules/workers (fibermall, vcelink, opticsbay) → 61 total workers - index-pi.ts: Pi fleet picks up all 3 new scrapers
