Phase 10: implement neoforge-26_1 leaf (WS, deltas, chat, link, reconciliation, player tracking)

Browse Source 
Ports the full feature set proven by the two legacy leaves to modern, post-Flattening
NeoForge (loader assumption confirmed: NeoForge 26.1.2.94 is real and published).
Neoforge261ChunkAdapter reads BlockState via LevelChunk/LevelChunkSection instead of raw
id+meta, carrying the full packed state id in DeltaEvent#blockStateId (a lossless int,
unlike the pre-Flattening 16-bit encoding) while documenting a known truncation caveat for
SectionData's char[]-based 3D backfill on very large modded registries. MCMapperMod uses
constructor-injected event buses (IEventBus/ModContainer) and NeoForge.EVENT_BUS instead of
@Mod.EventHandler methods, ModConfigSpec instead of legacy Configuration, and LinkCommand is
a Brigadier registration (no CommandBase in this era) fired from RegisterCommandsEvent.
Tracks its own loaded-chunk set via ChunkEvent.Load/Unload rather than querying chunk
provider internals (no stable public API for that in modern MC).

Gets its own standalone Gradle wrapper + settings.gradle (Foojay toolchain resolver) since
ModDevGradle needs Gradle 8+ and a Java 25 toolchain (MC itself now requires Java 25),
incompatible with the legacy leaves' Gradle-7/JDK-8 pin in one invocation.

Verified against real NeoForge 26.1.2.94 + decompiled MC 26.1.2 source via
./gradlew build from inside neoforge-26_1/ (two real API mismatches caught and fixed by
the compiler: ChunkPos is now a record — x()/z() methods, not fields — and
ResourceLocation was renamed to Identifier, ResourceKey#identifier() not #location()).
