Initial commit — Krunker Civilian Client
Cross-platform Krunker.io game client forked from Krunker Police Client with all KPD/moderator features stripped: no KPD auth, OBS recording, evidence uploads, yt-dlp, bytenode, or code obfuscation. Retained: unlimited FPS (custom Electron 42), ad blocking, resource swapper, matchmaker, userscripts, chat translator, Discord RPC, alt account manager, configurable keybinds, and advanced Chromium flags. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
