v1.0.1

Add Twitch EventSub WebSocket client to receive channel point redemption events and normalize them into chat messages; integrate it into TwitchService to subscribe/unsubscribe per-channel. Add a frameless standalone User Card window and a renderer entry (UserCardApp) to display user info and recent messages with mod actions. Implement 7TV cosmetics support: main-process fetch handler (avoids renderer CSP), renderer hook/service and settings toggles for badges/paints, and render 7TV badges/paints in MessageRow. Add chat search (Ctrl+F / Esc), reply UI tweaks, message rendering guards for redeems, message buffer cap per-channel to reduce merge cost, various UI/UX fixes, and bump package version to 1.0.1.
