FTB Quests Translator

### Added

- **Glossary (Translation Memory)**: You can now configure words to remain untranslated using `config/tfq_glossary.json`. Perfect for keeping mod names like "Redstone", "Create", or "Mekanism" in their original form. The system securely masks these words as `{{gX}}` tokens before sending them to the API, ensuring they don't break the grammatical context of the translated sentence.

- **Batch Translation**: Added two new buttons to the FTB Quests sidebar. You can now translate the entire questbook in the background. The mod uses a smart rate-limiting queue (1.5s delay) to avoid IP bans from free APIs. Progress is saved to `config/tfq_batch_progress.json`, allowing you to safely close the game and resume translation later.

- **Text-to-Speech (TTS) Voiceover**: Added a speaker icon next to the quest translation button. Clicking it reads the quest text aloud using Google TTS. It dynamically reads either the original English or the translated text, depending on your current view state. (Note: The icon will flash red if the language isn't supported for voiceover).

- **Regional Language Mapping**: The mod now correctly maps Minecraft's regional variants (like `es_mx` or `es_ar`) to their root API languages (`es`). For Chinese, it correctly splits between Simplified (`zh-CN`) and Traditional (`zh-TW`). The `[T]` tooltip in the language menu now informs users if they are using a mapped regional variant.

### Fixed

- **AUTO Provider Fallback Bug**: Fixed a critical issue where falling back from Google to MyMemory could cache garbage (`???`) if the target language wasn't actually supported by MyMemory (e.g., Kyrgyz `ky`). Added strict `supportsLanguage()` checks before fallback.

- **Config UI Title**: Fixed the raw translation key `ftbquesttransl.settings` showing up as the title in the FTB Quests configuration menu. It now properly displays "FTB Quests Translator Settings" (or localized equivalents).
