Invisibility Rework

This is a client-side Minecraft mod that changes what the Invisibility effect does visually, without removing or altering the effect itself.

In vanilla Minecraft, the Invisibility effect hides the entity model and nameplate from other players and mobs. This mod removes that visual suppression, so invisible players and mobs appear fully visible in-game. The effect tag remains on the entity untouched, which means third-party map plugins such as BlueMap, DynMap, and Squaremap — which detect player visibility by reading the Invisibility effect — will still correctly hide the player from the live map.

This mod was designed for a specific server scenario: servers that host live web maps (BlueMap, DynMap, Squaremap, etc.) where players can use the `/effect` command or Invisibility potions to hide themselves from the web map. Without this mod, those players also disappear from other players’ screens in-game, which may not be the desired behavior. With this mod, map-hidden players remain visible in-game so that normal PvP/PvE interaction is preserved.
