feat: unify queue execution handling with QueueItemExecutor and CLI execution settings

- Removed ad-hoc test scripts and temp files from project root
- Added QueueItemExecutor component to handle both session and orchestrator executions
- Created CliExecutionSettings component for shared execution parameter controls
- Introduced useCliSessionCore hook for managing CLI session lifecycle
- Merged buildQueueItemPrompt and buildQueueItemInstruction into a single function for context building
- Implemented Zustand store for queue execution state management
- Updated localization files for new execution features
