v1.2.0 - Domain Exclusions, Scrolling UI & Configurable Buffers

This release introduces domain and subdomain exclusions via a dynamic dropdown, significantly improves scroll pacing using a virtual physics scale, adds configurable 'safe zone' buffers for standard sites and reels, overhauls the popup UI with internal scrolling to bypass Chrome's constraints, and deploys a robust window-level interceptor to guarantee scroll-blocking on SPA feeds like YouTube Shorts and TikTok.
