docs: add comprehensive modder wiki (build-on-top guide) Replace the empty default Home with a 10-page modder guide covering all three extension tiers: - Home + _Sidebar navigation - Developer Setup (build, depend-on-PlayerMob, declare dependency) - Architecture Overview (Architectury split, per-loader registration + backfill) - Custom Skins (datapack JSON skin packs — no code) - Spawning & NBT (/summon keys, ordinals, allow-matrix, spawn eggs) - Personality System (Personality/TargetCategory/PersonalityProfile API) - Entity API Reference (PlayerMobEntity surface + reusable policy classes) - AI Goals (selector wiring, WeaponAwareAttackGoal pattern, extension caveats) - Soft-Dependency Integrations (TrainEnvironment seam + MENU_OPENER backfill) All facts verified against the v0.15.0 source.
