v1.2.0 — target MC 26.1.2

User reported NoClassDefFoundError: net/minecraft/class_7471 on MC 26.1.2.
Root cause: v1.1.1 was built for 1.21.6 intermediary, which uses
class_NNNN obfuscated names. MC 26.x ships an unobfuscated server jar
with Mojang names directly, so intermediary lookups for class_7471
(=PlayerChatMessage in 1.21.6) fail at runtime.

Build retargeted to 26.1.2:
- minecraft 26.1.2 / loader 0.19.2 / fabric-api 0.148.2+26.1.2
- Loom 1.16-SNAPSHOT, Shadow 9.4.1 (Java 25 bytecode support)
- Gradle 9.5.1, JDK 25 toolchain
- Drop officialMojangMappings(); use intermediary:0.0.0 identity
  (Mojang stopped publishing proguard mappings for 26.x).
- Adapt code: ServerPlayer.getServer() removed in 26.1.2 → use
  player.level().getServer() (ServerPlayer.level() returns ServerLevel).
- NeoForge dropped from this build — moddev plugin can't parse 26.1.2
  yet, falls back to 1.21.5.
- 1.2.0 = Fabric only; 1.21.6 users stay on 1.1.1.
