- Extracted OpenAI compatibility detection and resolution logic into dedicated `openai-completions-compat` module. - Refactored `detectCompat()` and `getCompat()` to delegate to new compat module functions with simplified conditional logic. - Fixed OAuth redirect URI validation to preserve exact configured values without trailing slash normalization. - Improved session deletion to return boolean status and display error messages in UI instead of silently failing. - Added `/session delete` command with Delete key support and confirmation dialogs for session management.
