feat: Streamline agents to pure executor roles with enhanced workflow architecture

## Agent Streamlining
- **code-developer.md**: Reduce from 315 to 122 lines - pure code execution focus
- **action-planning-agent.md**: Reduce from 502 to 124 lines - pure planning execution
- Remove complex decision logic - commands layer now handles control flow
- Add clean code rules: minimize debug output, GBK compatibility, ASCII-only

## Workflow Architecture Enhancements
- Enhanced workflow-architecture.md with progressive complexity system
- Clear separation: Commands (control) → Agents (execution) → Output
- Improved task decomposition and TODO_LIST.md examples
- Added Gemini CLI standards references

## Command System Updates
- Updated task and workflow commands with enhanced functionality
- Better integration with streamlined agents
- Improved error handling and user experience

 **Purpose**: Thorough upfront planning reduces risk, improves quality, and prevents costly rework.
 
-**Mandatory Triggers**: Planning is required for tasks spanning:
-- >3 modules or components
-- >1000 lines of code 
-- Architectural changes
-- High-risk dependencies
-
-**Key Deliverables**:
-- `IMPL_PLAN.md`: Central planning document for all complexity levels
-- Progressive file structure based on task complexity
-- `.summaries/`: Automated task completion documentation
-- `.chat/`: Context analysis sessions from planning phase
-
 ### TodoWrite Coordination Rules
 
 1.  **TodoWrite FIRST**: Always create TodoWrite entries *before* agent execution begins.
