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.
