Lumen Java 1.0.0-beta.3 - No Attack Cooldown

Adds No Attack Cooldown to Insert → Features, with an ON/OFF toggle and saved settings. It defaults to OFF, including when upgrading an existing configuration.

In private singleplayer worlds, enabling it gives your melee attacks full recharge strength immediately. The integrated server uses that strength for actual damage; this does not merely hide the attack indicator. Turning it off immediately restores normal charge calculations. Only your own player is affected.

Singleplayer only: inactive on remote servers and multiplayer/LAN worlds. Target damage immunity, missed-swing delays, item-use cooldowns and attack animations retain their normal behavior. Weapon damage/attack-speed attributes and persisted world data are not overwritten.

Validated in isolated Minecraft 26.3 game tests, both with and without Iris/Complementary Reimagined. An unenchanted iron axe dealt 9.0 damage fully charged, about 1.8 on an uncharged vanilla attack, 9.0 on consecutive attacks against fresh targets with the option enabled, and about 1.8 again after disabling. UI, persistence, world re-entry, other-player scope and existing Xray/Zoom/Fullbright regression checks passed. All eleven unit tests passed. Detailed verification.

Update: close Minecraft and replace the old Lumen JAR in your Prism instance's minecraft/mods folder with lumen-java-1.0.0-beta.3.jar. Keep Fabric API installed. Existing settings are retained.

Requires Minecraft 26.3, Java 25, Fabric Loader 0.19.5+ and Fabric API 0.161.0+26.3. Install on the client only. No in-game automatic updater. The source ZIP is for development; install only the mod JAR.
