Local AI model downloads now request Hugging Face access only after the user explicitly enables local model downloads. This reduces permissions shown during installation while keeping local SLM and RAG features available on demand.

This release improves the reader, AI assistant, localization, and Firefox compatibility.

• Improved AI provider setup, connection feedback, validation, and modern model guidance.
• Expanded and corrected translations across supported languages.
• Improved chatbot reliability with local and OpenAI-compatible providers.
• Improved page-progress estimates and reading-tracker stability.
• Refined Zen Mode behavior and its exit guidance.
• Improved compatibility and security hardening for Firefox extension packaging.
• EPUB scripts are now disabled for safer reading of local books.
• Removed legacy bundle fallbacks and unnecessary compatibility assets.

Compatibility: this version requires Firefox 142 or later.
