* refactor: Improve UX for Command Popovers
* Added loading state handling in Mention and PromptsCommand components to display a spinner when data is being fetched.
* Refactored onFocus logic to clear the textarea and set the search value based on command character input.
* Introduced a new `isLoading` state in the useMentions hook to manage loading indicators across multiple data queries.
* Added unit tests for the useHandleKeyUp hook to ensure command triggering works correctly under various conditions.
* ci: useHandleKeyUp tests for command navigation
* Added tests to ensure that the command popovers do not trigger when the cursor is mid-text after pressing ArrowLeft or Delete.
* Updated the shouldTriggerCommand function to refine the conditions under which commands are triggered based on cursor position.
* Improved agent query handling in useMentions hook for better performance and clarity.
* refactor: Optimize Mention and PromptsCommand Components
* Refactored Mention and PromptsCommand components to utilize Recoil state for popover visibility, improving state management and reducing prop drilling.
* Simplified onFocus logic to enhance user experience when interacting with command inputs.
* Added unit tests for useHandleKeyUp to ensure proper command handling and popover visibility based on user input.
* Improved performance by memoizing popover state and reducing unnecessary re-renders.
* fix: Address review findings for command popover refactor
- Fix endpointType regression: add effectiveEndpointByIndex selector
that returns endpointType ?? endpoint, matching the original ChatForm
guard for custom endpoints proxying assistants
- Extract duplicated initInputRef callback into shared useInitPopoverInput
hook, used by both Mention and PromptsCommand
- Add navigation keys (ArrowLeft, ArrowRight, ArrowDown, Home, End,
Delete) to invalidKeys to prevent false popover triggers
- Add endpoint gating tests for assistants/azureAssistants blocking the
+ command
- Remove unused _index param from MentionContent
