Whats Next? 0.18.0 - STRUCTURE AND CONSISTENCY AUDIT

- Split LootTracker/UI.lua into Common, Browse, MyLoot and Controller modules.
- Split UI/TaskList.lua into Filters, Rows and Views modules.
- Added logical UI/Tasks and LootTracker/UI folders.
- Moved historical release notes to Docs/Releases (not loaded by WoW).
- Updated addon TOC description and About page to match current features.
- Updated Equipment Loot Test help text to match strict HIGH/BIS + independent Void Core behavior.
- Preserved SavedVariables schema and existing tracked loot/task data.
- No custom UI scaling was added; Blizzard/UIParent scaling remains authoritative.
