feat(pipeline): add WTRG (Wowee Area Trigger) format

Novel open replacement for Blizzard's AreaTrigger.dbc +
AreaTriggerTeleport.dbc + the AzerothCore-style
areatrigger_template / areatrigger_teleport SQL tables.
The 29th open format added to the editor.

Defines proximity-based event zones — when a player enters
a defined region (box or sphere), the runtime fires the
trigger's action: teleport to another map, award
exploration XP for a quest, run a server script, gate an
instance entrance behind a key item, mark a PvP boundary,
or simply display a "Discovered: {area name}" banner.

Cross-references with previously-added formats — every
trigger field has a real format target:
  WTRG.entry.mapId / areaId  -> WMS.map.mapId / WMS.area.areaId
  WTRG.actionTarget (Teleport)        -> WMS.mapId
  WTRG.actionTarget (QuestExploration) -> WQT.questId
  WTRG.requiredQuestId       -> WQT.entry.questId
  WTRG.requiredItemId        -> WIT.entry.itemId (key)

Format:
  • magic "WTRG", version 1, little-endian
  • per trigger: triggerId / mapId / areaId / name /
    center vec3 / shape / kind / boxDims vec3 / radius /
    actionTarget / dest vec3 / destOrientation /
    requiredQuestId / requiredItemId / minLevel

Enums:
  • Shape (2): Box / Sphere
  • Kind (7): Teleport / QuestExploration / Script /
              InstanceEntrance / AreaName / CombatStartZone /
              Waypoint

API: WoweeTriggerLoader::save / load / exists / findById.

Three preset emitters showcase common trigger shapes:
  • makeStarter    — area-name + quest-exploration with
                      cross-ref to WQT 100 ("Investigate the
                      Camp")
  • makeDungeon    — outdoor area-name + portal-style
                      InstanceEntrance with Deadmines key
                      gate (WIT itemId 5200, matches
                      WLCK.makeDungeon's Boss Vault Seal) +
                      interior exit teleport back outdoors
  • makeFlightPath — 2 sphere waypoints near flight masters
                      so the runtime can auto-open the
                      flight UI on proximity (matches WTAX
                      starter node positions)

CLI added (5 flags, 601 documented total now):
  --gen-triggers / --gen-triggers-dungeon / --gen-triggers-flightpath
  --info-wtrg / --validate-wtrg

Validator catches: triggerId=0 + duplicates, unknown shape /
kind, non-finite center, sphere with radius<=0, box with
all-zero half-extents, teleport / instance with dest=(0,0,0)
(silently does nothing — usually a typo), QuestExploration
without an actionTarget questId.
