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
