fix(LuaEngine): Fix quest objective progress not updating in Player:CompleteQuest

[forgives]

Problem

After completing a quest via player:CompleteQuest(questId) (e.g., QuestCompleter.lua's .qc command), the quest status changes to complete, but objective progress (e.g., "Creature slain 0/1", "GO interaction 0/1") still shows 0, causing inconsistent in-game display. Quests involving GameObjects (e.g., quest 553 "Helnclaw's Revenge") cannot be completed through this API at all.

Root Cause

The ALE CompleteQuest binding has several bugs:

1. GO entry sign conversion bug (direct cause): KillCreditGO(creature) passes a negative int32 that implicitly converts to a huge uint32 , never matching the positive GO entry in the quest template.
2. Item count underflow : GetItemCount(id, true) includes bank items, and count - curItemCount underflows when curItemCount > count . Reward validation only checks the inventory, so bank items should not be counted.
3. Objectives not filled by gap : Always loops the full RequiredNpcOrGoCount times; repeated calls trigger extra achievement updates and script hooks. Money is also fully replenished each call.
4. Missing objective types : Does not handle QUEST_SPECIAL_FLAGS_PLAYER_KILL or QUEST_SPECIAL_FLAGS_EXPLORATION_OR_EVENT .
5. Unconditional CompleteQuest at end : Credit APIs may auto-complete the quest when the last objective is satisfied; calling it again triggers duplicate script hooks, aura updates, and quest tracker writes.
6. Insufficient entry guard : Only excludes QUEST_STATUS_NONE , allowing revival of failed quests.
   Fix

• Fix GO entry conversion using int64 intermediate to take absolute value, eliminating both the sign bug and INT32_MIN UB.
• Fill all objectives (items, creature/GO, player kills, reputation, money) by querying current progress and only补 the gap — near-idempotent on repeated calls.
• Add missing player kill ( KilledPlayerCreditForQuest ) and exploration/event ( AreaExploredOrEventHappens ) objective handling.
• Align reputation branch with official cs_quest.cpp : use int32 comparison and static_cast for SetReputation .
• Guard entry and post-credit with QUEST_STATUS_INCOMPLETE checks to prevent reviving failed quests.
• Wrap final CompleteQuest call with status guard to avoid duplicate side effects.
• Change item count to inventory-only ( GetItemCount(itemId) ).
  Scope

Only affects the explicit player:CompleteQuest() path; does not modify the AzerothCore native quest system. GO quests go from completely broken to working; repeated calls are now safe and near-idempotent.

Walkthrough

PlayerMethods::SetGlyph now removes the previous glyph aura before replacing the glyph and applies the new glyph’s spell aura afterward when valid definitions exist.

Validate slotIndex before accessing glyph storage.

MAX_GLYPH_SLOT_INDEX is 6, and glyph storage has six slots. Reject slotIndex >= MAX_GLYPH_SLOT_INDEX before Player::GetGlyph in both SetGlyph and GetGlyph; otherwise the narrowed value can access invalid storage.
