feat: Add Codex CLI support as alternative analysis method in workflow system

## Major Changes
- Add --AM flag to /workflow:plan command for analysis method selection
- Support both Gemini CLI (pattern-based) and Codex CLI (autonomous) analysis
- Implement dual marker system: [GEMINI_CLI_REQUIRED] and [CODEX_CLI_REQUIRED]
- Update all 4 agents to handle both analysis markers
- Create analysis method templates for standardized CLI usage

## Files Modified
- workflow-architecture.md: Add Analysis Method Integration section
- plan.md: Add --AM flag and bilingual rule standardization
- execute.md: Update marker mapping logic and standardize to English
- 4 agent files: Add dual CLI support with usage guidelines
- New: analysis-methods/ templates for Gemini and Codex CLI

## Backward Compatibility
- Gemini CLI remains default analysis method
- Existing workflows continue to work unchanged
- Progressive enhancement for autonomous development scenarios

 ### Detection and Activation
-When receiving task prompt, check for GEMINI_ANALYSIS_REQUIRED flag:
-- **If GEMINI_ANALYSIS_REQUIRED: true** - Execute mandatory Gemini CLI analysis
+When receiving task prompt, check for analysis markers:
+- **[GEMINI_CLI_REQUIRED]** - Execute mandatory Gemini CLI pattern-based analysis
+- **[CODEX_CLI_REQUIRED]** - Execute mandatory Codex CLI autonomous analysis
 - **ASSIGNED_ROLE** - Extract the specific role for focused analysis
 - **ANALYSIS_DIMENSIONS** - Load role-specific analysis dimensions
 
 ### Execution Logic

+    topic = extract_topic(prompt)

         for dimension in dimensions:
             result = execute_gemini_cli(

             )
             integrate_to_role_output(result, role)
