- Introduced `xai-api-key` to configuration for supporting xAI provider integration.
- Added API key operations: creation, updates, deletion, and sanitization.
- Implemented backend enhancements for credential-specific routing, response filtering with model aliasing, and WebSocket handling for xAI services.
- Included extensive test coverage to validate configuration parsing, CRUD operations, and the new functionalities.
- Updated related modules to handle `xai-api-key`, including the watcher, management handlers, and configuration sanitizers.
- Replaced PKCE-based OAuth for xAI with device authorization flow for enhanced compatibility.
- Introduced cancelable OAuth sessions with server-side invalidation to prevent token persistence on flow interruption.
- Updated OAuth polling and session tracking to handle device flow specifics, such as `user_code` and extended timeouts.
- Refactored TUI OAuth model to track polling generations, distinguish device flow, and handle session cancellation gracefully.
- Extended test cases for device flow scenarios, stale session handling, and cancelation logic.
- Streamlined xAI device flow management in handler logic and improved error handling.
- Introduced API handlers and executor logic for Google Interactions
- Added request and response transformations for OpenAI and Claude Interactions.
- Integrated Gemini API with Interactions support.
- Updated tests to validate Interactions request parsing and error handling.
- Refactored translator logic for Interactions data flows.
- Deleted the `LoggerPlugin` along with associated usage tracking and in-memory statistics logic.
- Removed all related tests (`logger_plugin_test.go`, `usage_tab_test.go`) and external-facing handler (`usage.go`) for usage statistics export/import.
- Cleaned up TUI integration by deleting `usage_tab.go`.
- Implemented `--standalone` mode to launch an embedded server for TUI.
- Enhanced TUI client to support API-based log polling when log hooks are unavailable.
- Added authentication gate for password input and connection handling.
- Improved localization and UX for logs, authentication, and status bar rendering.
