Duo Addon Manager

### Duo Addon Manager - v1.0.2 Release Notes

- **New: Full i18n Localization Engine**:
  - Automatically adapts to client locale. Native English UI for global clients (`enUS`/`enGB`/others) and refined Chinese UI for `zhCN`/`zhTW`.
  - Bilingual mapping for all 10 official Curse categories without breaking preset filtering.
  - Complete localization across all UI elements: Title, Search, Batch Operations, Profile management, Addon Badges (`Core`, `items`, `Hide`, `LOD`), and Minimap Dock.
- **TOC Compatibility**:
  - Updated for Retail 12.1 (`Interface: 120100, 120105, 120000`). No more "out of date" warnings.
  - Standardized blizzard TOC metadata (`Title-zhCN/enUS`, `Notes-zhCN/enUS`, `Category-zhCN/enUS`).
- **Performance & Stability**:
  - Zero-garbage-collection hash lookups with metatable fallbacks to prevent missing-key Lua errors.
  - Smooth search debouncing and session-persistent sort snapshots.
