Drop mappings declaration for unobfuscated 26.2

Starting with 26.1 Mojang ships Minecraft unobfuscated, and Yarn /
Intermediary are no longer published past 1.21.11. Loom does not need
a mappings dependency in that mode: the Mojang-named source compiles
directly. Remove the mappings line, drop the yarn_mappings property,
revert the client entrypoint to Mojang names (Minecraft, Component,
ChatFormatting, gui.getChat(), getUser().getName()), and rewrite the
README note so it stops claiming Mojang mappings via Loom.

 Дата релиза `Minecraft 26.2`: `2026-06-16`.
 
-Для этой версии я использую official Mojang mappings через Loom, потому что стандартный Yarn endpoint для `26.2` на момент правки ещё не отдавал mappings.
+Начиная с `26.1` Mojang перестал обфусцировать клиент, а Yarn и Intermediary перестали публиковаться после `1.21.11`. Поэтому в `build.gradle` нет блока `mappings` вообще: исходники Minecraft уже в человекочитаемых именах Mojang, и Loom собирает мод напрямую против них.
 
 Если в CI стоит старый Loom вроде `1.10.5`, сборка `26.2` упадёт с ошибкой `Unsupported class file major version 69`. Для `26.2` нужен новый Loom из актуальной ветки Fabric.
