refactor: Reduce duplication in brainstorming system

- Create brainstorming-framework.md to centralize common techniques and execution modes
- Simplify conceptual-planning-agent.md from 280 to 170 lines (39% reduction)
- Update all 9 brainstorm commands to reference framework instead of agent
- Eliminate circular dependencies and improve maintainability

Key improvements:
- Separated concerns: principles -> framework -> commands -> agent
- Role definitions now only exist in their respective command files
- Creative techniques centralized in framework file
- Agent focused solely on execution logic
- Clear hierarchical reference structure without duplication

+## Brainstorming Session Protocol
+
+### Input Processing
+```
+Topic: [Challenge or opportunity description]
+Mode: [creative|analytical|strategic]
+Perspectives: [Selected role perspectives]
+Context: [Current situation and constraints]
+```
+
+### Execution Flow
+```
+1. Challenge Analysis → Define scope, constraints, success criteria
+2. Perspective Setup → Establish role contexts and viewpoints
+3. Ideation Phase → Generate ideas using appropriate techniques
+4. Convergence Phase → Evaluate, synthesize, prioritize solutions
+5. Documentation → Create structured session records
+```
+
+## Documentation Standards
+
+### Session Summary Generation

+- Challenge definition and scope
+- Key insights and patterns
+- Generated ideas with descriptions
+- Perspective analysis from each role
+- Evaluation and prioritization
+- Recommendations and next steps
+
+### Idea Documentation

+- Feasibility assessment (technical, resource, timeline)
+- Impact potential (user, business, technical)
+- Implementation considerations and prerequisites
+- Success metrics and validation approach
+- Risk assessment and mitigation strategies
+
+## Output Format Standards

+
+## Integration Guidelines
+
+### With Brainstorming Principles
+This framework works in conjunction with @~/.claude/workflows/brainstorming-principles.md which defines:
+- Project structure establishment
+- Session initialization requirements
+- Directory creation protocols
+- Agent coordination standards
+
+### With Role Commands
+Each role-specific brainstorm command implements this framework within their domain context:
+- Applies appropriate techniques for their perspective
+- Uses mode selection based on problem type
+- Follows documentation standards
+- Maintains quality criteria
+
+---
+
+This framework provides the common foundation for all brainstorming activities while allowing role-specific customization and focus.
