feat: Add plan-deep command and Gemini analysis integration

- Create /workflow:plan:deep command for deep technical planning
- Add GEMINI_ANALYSIS_REQUIRED support to conceptual-planning-agent
- Translate brainstorm commands to English (business-analyst, partial innovation-lead)
- Consolidate document format standards in file-structure-standards.md
- Update action-planning-agent to reference centralized format standards

Key changes:
- plan-deep.md: New command with mandatory Gemini CLI analysis via agent
- conceptual-planning-agent.md: Added Gemini Analysis Integration section
- file-structure-standards.md: Enhanced with detailed IMPL_PLAN.md formats
- Unified language to English for consistency

+### Detection and Activation
+When receiving task prompt, check for GEMINI_ANALYSIS_REQUIRED flag:
+- **If GEMINI_ANALYSIS_REQUIRED: true** - Execute mandatory Gemini CLI analysis
+- **ASSIGNED_ROLE** - Extract the specific role for focused analysis
+- **ANALYSIS_DIMENSIONS** - Load role-specific analysis dimensions

+        role = extract_value("ASSIGNED_ROLE", prompt)
+        dimensions = extract_value("ANALYSIS_DIMENSIONS", prompt)

+| ui-designer | user_flow_patterns, component_reuse, design_system_compliance | UI/UX patterns and consistency |
+| business-analyst | process_optimization, cost_analysis, efficiency_metrics, workflow_patterns | Business process and ROI |
+| data-architect | data_models, flow_patterns, storage_optimization | Data structure and flow |
+| security-expert | vulnerability_assessment, threat_modeling, compliance_check | Security risks and compliance |
+| user-researcher | usage_patterns, pain_points, behavior_analysis | User behavior and needs |
+| product-manager | feature_alignment, market_fit, competitive_analysis | Product strategy and positioning |
+| innovation-lead | emerging_patterns, technology_trends, disruption_potential | Innovation opportunities |
+| feature-planner | implementation_complexity, dependency_mapping, risk_assessment | Development planning |

+### Output Integration
+Gemini analysis results are integrated into the single role's output:
+- Enhanced `analysis.md` with codebase insights
+- Role-specific technical recommendations
+- Pattern-based best practices from actual code
+- Realistic feasibility assessments based on current implementation
