chore: add BMAD agent workflows and configuration system

- Add comprehensive agent workflow definitions for 8 specialized roles (analyst, architect, developer, product manager, scrum master, technical writer, UX designer, QA engineer)
- Add 35+ workflow definitions covering analysis, planning, solutioning, and implementation phases
- Add BMAD configuration system with agent, task, tool, workflow, and file manifests
- Add BMM (Business Model Methodology) documentation including quick-start guides, architecture references, and workflow analysis
- Add test architecture knowledge base with 20+ testing patterns and best practices
- Add team configuration templates and party mode setup for collaborative development
- Establish foundation for enterprise agentic development framework with adaptive scaling capabilities

+
+✅ Story file updated: `{{story_file}}` → Status: ready-for-dev
+✅ Sprint status updated: drafted → ready-for-dev
+
+**Story Details:**
+
+- **ID:** {{story_id}}
+- **Key:** {{story_key}}
+- **Title:** {{story_title}}
+- **File:** `{{story_file}}`
+- **Status:** ready-for-dev
+
+**Next Steps:**
+
+1. **Recommended:** Run `story-context` workflow to generate implementation context
+   - This creates a comprehensive context XML for the DEV agent
+   - Includes relevant architecture, dependencies, and existing code
+
+2. **Alternative:** Skip context generation and go directly to `dev-story` workflow
+   - Faster, but DEV agent will have less context
+   - Only recommended for simple, well-understood stories
+
+**To proceed:**
+
+- For context generation: Stay with SM agent and run `story-context` workflow
+- For direct implementation: Load DEV agent and run `dev-story` workflow
+
+</step>
