v0.2.0

Hardening release. Fixed: SPA text replacement now transforms; mode/settings changes take effect; URLs, emails, and long unbroken runs are skipped; settings broadcast to every tab; scroll-reveal can never leave content hidden (print + observer fallback). Added: toolbar badge, nav/button skipping, site motion, how-to and privacy pages, store listing kit, benchmark, and a full README. 100 tests, web-ext 0/0/0, e2e 6/6.
