Enhance CLI Lite Planning Agent with Mandatory Quality Check

- Added Phase 5: Plan Quality Check to cli-lite-planning-agent.md, detailing mandatory quality validation after plan generation.
- Introduced quality dimensions: completeness, granularity, dependencies, acceptance criteria, implementation steps, and constraint compliance.
- Specified CLI command format for quality check execution and expected output structure.
- Implemented result parsing and auto-fix strategies for minor issues.
- Updated integration flow to ensure quality check is executed before returning the plan to the orchestrator.

Refactor lite-plan.md to reflect internal quality check execution for medium/high complexity plans.

Create new brainstorm-with-file.md for interactive brainstorming workflow, detailing session setup, execution process, and implementation steps.
