feat(pipeline): add WQT (Wowee Quest Template) format

Novel open replacement for AzerothCore-style quest_template
SQL tables PLUS the Blizzard Quest.dbc / QuestObjective.dbc
trio. The 15th open format added to the editor — and the
last gameplay-graph piece the catalog needed.

Cross-references with previously-added formats:
  WQT.giverCreatureId    -> WCRT.entry.creatureId
  WQT.turninCreatureId   -> WCRT.entry.creatureId
  WQT.objective.targetId -> WCRT (kill) / WIT (collect) /
                             WOB (interact)
  WQT.rewardItem.itemId  -> WIT.entry.itemId
  WQT.prevQuestId        -> WQT.entry.questId (intra-format)
  WQT.nextQuestId        -> WQT.entry.questId

Together with WIT / WCRT / WLOT / WSPN / WOMX / WOL / WOW /
WSND, a content pack can now ship a complete RPG zone
(terrain + props + atmosphere + sounds + creatures + items
+ loot + spawns + quests) entirely in open formats with no
SQL or .dbc dependencies. 15 of 15 expected slots filled.

Format:
  • magic "WQTM", version 1, little-endian
  • per quest: questId / title / objective / description /
    minLevel..maxLevel + questLevel / requiredClass+RaceMask /
    prev+nextQuestId / giver+turninCreatureId /
    objectives[] / xpReward + moneyCopperReward /
    rewardItems[] / flags

Per-objective:
  kind (kill/collect/interact/visit/escort/cast),
  targetId, quantity

Per-reward:
  itemId, qty, pickFlags (AutoGiven / PlayerChoice)

Quest flags: Daily / Weekly / Raid / Group / AutoComplete /
              AutoAccept / Repeatable / ClassQuest / Pvp

API: WoweeQuestLoader::save / load / exists / findById;
presets makeStarter (1 simple kill quest, references the
bandit creatureId=1000), makeChain (3-quest chain with
prev/next links + AutoComplete bridge + player-choice
rewards), makeDaily (Daily+Repeatable+AutoAccept combo).

CLI added (5 flags, 500 documented total — round milestone):
  --gen-quests / --gen-quests-chain / --gen-quests-daily
  --info-wqt / --validate-wqt

Validator catches: questId=0+duplicates, level=0,
maxLevel<minLevel, empty title, no objectives without
AutoComplete (player can't finish), no rewards at all,
Daily without Repeatable (incoherent), targetId=0,
quantity=0, unknown objective kind, reward itemId=0 or qty=0.

The 3-quest chain demo exercises every major feature:
  • multiple objective kinds (visit / collect / kill)
  • prev/next chain links
  • AutoComplete dialogue-bridge quest
  • PlayerChoice reward (1 of 2 weapons)
