feat(workflow): add lightweight interactive planning workflow with in-memory execution and code exploration

- Introduced `lite-plan` command for intelligent task analysis and planning.
- Implemented dynamic exploration and clarification phases based on task complexity.
- Added support for auto mode and forced exploration flags.
- Defined output artifacts and session structure for planning results.
- Enhanced execution process with context handoff to `lite-execute`.

chore(temp): create temporary memory content and import script

- Added `.temp-memory-content.txt` to store session details and execution plan.
- Implemented `temp-import-memory.cjs` to handle memory import using core-memory command.
- Ensured cleanup of temporary files after execution.
