v1.1.0 — Smarter scanning, fewer false positives, more sites supported

New features:
- Background script that intercepts API responses from SPA-heavy retail sites
- Persistent scan cache — previously scanned products load instantly on revisit
- Parallel scanning (4x faster on large product listings)
- SPA navigation detection — pagination and client-side routing now trigger rescans automatically
- "Click a product to scan" message on sites where gallery scanning isn't possible (Old Navy, Gap, H&M)

Smarter detection:
- Composition-aware scanning — products declaring "100% cotton" or similar natural fibers won't get false flagged even if the page discusses synthetics in marketing copy
- Negation detection — phrases like "no polyester", "polyester-free", and "polyester haters" are correctly ignored
- Educational context filtering — comparison tables and anti-synthetic marketing copy no longer trigger false positives
- Structured material data is prioritized over full-page text scanning

Visual improvements:
- Redesigned status pill with scanning progress bar and glass blur effect
- Dimmed cards now hover-to-reveal for quick comparison
- Fixed an issue where images disappeared entirely on some sites
- Carousel and slider elements are handled correctly and no longer get oversized badges

Compatibility:
- Added credential-aware fetching for Etsy and REI
- Improved product link discovery for sites using query-parameter URLs
- Better support for Shopify, Demandware, and custom ecommerce platforms
- Added REI, Etsy, Bombas, PopFlex, NADS, and many more to tested sites
