Refactor and optimize various components and files

- Removed deprecated `ccw-contentPattern-optimization-summary.md` and related files.
- Updated `A2UIPopupCard.tsx` to clarify comments on interaction handling.
- Enhanced `QueueListColumn.tsx` and `QueuePanel.tsx` to handle potential undefined values for `config`.
- Added `useEffect` in `QueuePanel.tsx` to load scheduler state on mount.
- Improved `SchedulerPanel.tsx` to handle potential undefined values for `sessionPool`.
- Introduced auto-initialization logic in `queueSchedulerStore.ts` to prevent multiple initialization calls.
- Updated `A2UIWebSocketHandler.ts` to refine selection handling logic.
- Enhanced `hooks-routes.ts` to support multi-question surfaces.
- Added submit and cancel buttons in `ask-question.ts` for better user interaction.
- Deleted `codex_prompt.md` and `contentPattern-library-options.md` as part of cleanup.
- Removed `status-reference.md` to streamline documentation.
