Xurkon 05ea31bc53 perf: reduce CPU hotspots identified in profiler
- HBD.lua: Cache GetPlayerWorldPosition/GetPlayerZonePosition at 50ms
  intervals instead of hammering GetPlayerMapPosition() every frame.
  Invalidate cache on PLAYER_ENTERING_WORLD and ZONE_CHANGED_* events.
  Expected ~97% reduction in C API position calls (45,570 -> ~1,200 / 10min).

- zoneDB.lua: Replace O(n) linear scan in GetAreaIdByUiMapId with an
  O(1) reverse lookup cache (uiMapIdToAreaIdCache) built at Initialize().
  Cache is kept in sync by ApplyCustomZones and name-match fallback now
  caches its result so subsequent calls are also O(1).

- Tooltip.lua: Throttle GameTooltip OnUpdate hook to 100ms intervals
  (was firing every frame at 60-144 Hz). Added _tooltipLastText cache
  to avoid redundant GetText() + CountTooltip() calls when nothing changed.

- QuestieArrow.lua: Hoist _HasMissingCompletedFlag, _GetCompleteIconType,
  _CollectFinisherSpawns, and _CollectObjective out of _CollectQuestTargets
  to module-level functions. These were re-created as closures on every
  UpdateNearestTargets call (1 Hz). Shared per-cycle context is published
  via _arrow_* module upvalues to avoid closure capture overhead.

- QuestieLearnerComms.lua: Four micro-optimizations:
  (1) Reduce ProcessQueues ticker 0.2s -> 0.5s (still 7x faster than
      minChatInterval of 3.5s).
  (2) Cache hidden channel ID at init; lazy refresh on disconnect.
  (3) Drop LibDeflate compress level 9 -> 1 (fraction of CPU cost).
  (4) O(1) messageCacheCount counter replaces O(n) pairs() size scan.
