- 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.
