Rosseta 2.0 is a full rewrite of how the extension connects to AI providers. It adds many more providers, multiple API keys per provider, and a proper model manager.

IMPORTANT — YOUR EXISTING SETUP WILL RESET
The old single-key login flow has been replaced. API keys, custom providers, and model choices from 1.x are not carried over. After updating, please re-add your API key under Manage API Keys and pick a model under Manage Models.

NEW IN 2.0
- 11 built-in providers: Google, Groq, xAI, OpenAI, Anthropic, Mistral, DeepInfra, Z.ai, OpenRouter, OpenCode, and Hugging Face.
- Multiple API keys per provider, with key-selection modes: single key, round-robin, or auto-balance.
- Custom OpenAI-compatible endpoints: connect any API with your own base URL, optional headers, and optional query parameters.
- New Manage Models page: fetch the live model list from the provider, add models manually, and choose the active model per provider. Your choices survive browser restarts.
- Redesigned Manage API Keys page with a per-provider view and a search-or-add input.

IMPROVEMENTS
- The optional context description can now be turned off to save tokens.
- Added a retry path for models that don't support structured JSON output.
- Stale model selections are detected and repaired automatically after a model list refresh.
- Clearer errors for rate limits, authentication failures, and text-only models that can't read images.
- Translation output keeps each visual block (heading, caption, button) on its own line.
- Improved history search, and removed the duplicate Add button.
- The default shortcut changed from Ctrl+Space to Ctrl+Shift+Y (Command+Shift+Y on macOS). You can change it in your browser's extension shortcut settings.

REMOVED
- Proxy support has been removed.
- The separate login page and API-key validation step are gone; keys are now managed per provider.

FIXES
- Pressing Esc now cancels the region-selection overlay and no longer closes an open translation result.
- Choosing a specific API key now works even while auto-balance is enabled.
- Back navigation restored on the Manage Keys and Manage Models pages.
