* bot will not automatically download video from youtube or load it from cache. It will fetch video info first, then suggest to download or get video from cache (with retry options)
* some rewriting in sending/editing/replying to messages
Stop reading image files inside gemini/mistral commands; use pre-encoded image data from message parts
Rework loadImagesIfExists / loadImagesFromFileIds to return cached file_unique_ids and download only missing sizes
Encode cached images to base64 when assembling the reply chain
Make getPhotoMaxSize synchronous (returns PhotoSize), and map to URL only when needed
Await MessageStore.put / UserStore.put and prefetch single-image downloads on message receipt
- make MessageStore.put() return StoredMessage and allow collectReplyChainText() to work with StoredMessage
- move muted users + answers loading into Environment (add Answers model + GEMINI_IMAGE_MODEL)
- extract message handling into processNewMessage() and add media-group (album) caching/downloading by unique_file_id
- for Ollama: check model capabilities before sending images; use replyToMessage helper consistently
- add /geminiGenImage command stub for Gemini image generation
