Magic NPCs

[0.2.0] — NPC compatibility, hardening & magic schools

A broad release-readiness pass plus a new per-NPC magic-school system. Builds green and boots cleanly with or without Iron's/Recruits (offline GameTest bootSanity passes); runtime casting is unchanged from the proven 0.1.1 path.

Added

• Magic schools for recruits & villagers. Each individual recruit/villager can be assigned an Iron's school (fire, ice, lightning, holy, ender, blood, evocation, nature, eldritch). The spell pool is built dynamically from that school's enabled spells (filtered by rarity/level caps, INSTANT-only, and the allow/deny lists), so add-on spells are picked up automatically. Assignment is stored per-entity in persistent data and rolled once. See docs/schools.md.
  • Automatic on spawn — recruits by chance/rank/mode (RANDOM/BY_TYPE/BY_RANK), villagers by a profession→school map. Villagers only actually cast when they have a target (raids / guard mods), preserving vanilla passivity.
  • /magicnpcs school set|info|reroll|clear <targets> [school] command (perm-gated).
  • School Tome item — right-click an NPC to cycle its school, sneak to clear.
• Generic owner/team friendly-fire protection (targeting.protectOwners): a vanilla-only adapter (scoreboard teams + OwnableEntity) protects companion/pet/ follower NPCs (e.g. Human Companions) and their owner with no hard dependency.
• Generic bystander protection (targeting.protectBystanders): attack spells avoid catching villagers, iron golems, players, and tamed pets in their line of fire.
• Per-mod compat toggles ([compat], default off) gating datapack loadouts for Guard Villagers, MCA Reborn, MineColonies, Easy NPC, Human Companions, More Villagers, and VillagersPlus. A ready Guard Villagers loadout ships (inert until enabled); copy- paste examples for the rest are in docs/loadouts/.
• Equipment options ([equipment]): requireSpellFocus (NPC must hold an item in the magicnpcs:spell_focuses tag) and spawnWithGearChance.
• Lang file (en_us.json) with config labels + item text; item model reuses the vanilla enchanted-book texture (no third-party asset shipped).

Changed

• Casting hardening. NPCs no longer cast while sleeping, dead/dying, removed, or AI-disabled; attack spells now require line of sight (requireLineOfSight); casting is suppressed on Peaceful (peacefulDisablesCasting); mana pools scale with world difficulty (difficultyScaling).
• Recruits now respect their command system — a recruit ordered to a passive/flee state will not cast.
• bootSanity GameTest now ships its platform structure and passes offline.

Notes

• Iron's Spells 'n Spellbooks and Villager Recruits remain compile-only soft dependencies — neither is bundled. The 8 non-Recruits NPC mods are supported via config + datapack + generic vanilla-interface adapters (no API imports), so the mod loads safely whether or not they are installed.
