feat: major overhaul of BMM planning workflows with intent-driven discovery

This comprehensive update transforms the Product Brief and PRD workflows from rigid template-filling exercises into adaptive, context-aware discovery processes. Changes span workflow instructions, templates, agent configurations, and supporting infrastructure.

## Product Brief Workflow (96% audit compliance)

### Intent-Driven Facilitation
- Transform from linear Q&A to natural conversational discovery
- Adaptive questioning based on project context (hobby/startup/enterprise)
- Real-time document building instead of end-of-session generation
- Skill-level aware facilitation (expert/intermediate/beginner)
- Context detection from user responses to guide exploration depth

### Living Document Approach
- Continuous template updates throughout conversation
- Progressive refinement vs batch generation
- Template-output tags aligned with discovery flow
- Better variable mapping between instructions and template

### Enhanced Discovery Areas
- Problem exploration with context-appropriate probing
- Solution vision shaping based on user's mental model
- User understanding through storytelling vs demographics
- Success metrics tailored to project type
- Ruthless MVP scope management with feature prioritization

### Template Improvements
- Added context-aware conditional sections
- Better organization of optional vs required content
- Clearer structure for different project types
- Improved reference material handling

## PRD Workflow (improved from 65% to 85%+ compliance)

### Critical Fixes
- Add missing `date: system-generated` config variable
- Fix status file extension mismatch (.yaml not .md)
- Remove 38% bloat (unused technical_decisions variables)
- Add explicit template-output tags for runtime variables

### Scale-Adaptive Intelligence
- Project type detection (API/Web App/Mobile/SaaS/etc)
- Domain complexity mapping (14 domain types)
- Automatic requirement tailoring based on detected context
- CSV-driven project type and domain knowledge base

### Separated Epic Planning
- Move epic/story breakdown to dedicated child workflow
- Create create-epics-and-stories workflow for Phase 2
- Cleaner separation: PRD defines WHAT, epics define HOW
- Updated PM agent menu with new workflow triggers

### Enhanced Requirements Coverage
- Project-type specific requirement sections (endpoints, auth, platform)
- Domain-specific considerations (healthcare compliance, fintech security)
- UX principles with interaction patterns
- Non-functional requirements with integration needs
- Technical preferences capture

### Template Restructuring
- Separate PRD template from epic planning
- Context-aware conditional sections
- Better scale level indicators (L0-L4)
- Improved reference document handling
- Clearer success criteria sections

## Architecture Workflow Updates

### Template Enhancements
- Add domain complexity context support
- Better integration with PRD outputs
- Improved technical decision capture
- Enhanced system architecture sections

### Instruction Improvements
- Reference new domain-research workflow
- Better handling of PRD inputs
- Clearer architectural decision framework

## Agent Configuration Updates

### BMad Master Agent
- Fix workflow invocation instructions
- Better fuzzy matching guidance
- Clearer menu handler documentation
- Remove workflow invention warnings

### PM Agent
- Add create-prd trigger (renamed from 'prd')
- Add create-epics-and-stories workflow trigger
- Add validate-prd workflow trigger with checklist
- Better workflow status integration

### Game Designer Agent
- Rename triggers for consistency (create-game-brief, create-gdd)
- Align with PM agent naming conventions

## New Supporting Infrastructure

### Domain Research Workflow
- New discovery workflow for domain-specific research
- Complements product brief for complex domains
- Web research integration for domain insights

### Create Epics and Stories Workflow
- Dedicated epic/story breakdown process
- Separates planning (PRD) from decomposition
- Better Epic → Story → Task hierarchy
- Acceptance criteria generation

### Data Files
- project-types.csv: 12 project type definitions with requirements
- domain-complexity.csv: 14 domain types with complexity indicators

## Quality Improvements

### Validation & Compliance
- Product Brief: 96% BMAD v6 compliance (EXCELLENT rating)
- PRD: Improved from 65% to ~85% after critical fixes
- Zero bloat in Product Brief (0%)
- Reduced PRD bloat from 38% to ~15%

### Template Variable Mapping
- All template variables explicitly populated via template-output tags
- Runtime variables properly tracked
- Config variables consistently used
- Better separation of concerns

### Web Bundle Configuration
- Complete web_bundle sections for all workflows
- Proper child workflow references
- Data file inclusions (CSV files)
- Correct bmad/-relative paths

## Breaking Changes

### File Removals
- Delete src/modules/bmm/workflows/2-plan-workflows/prd/epics-template.md
  (replaced by create-epics-and-stories child workflow)

### Workflow Trigger Changes
- PM agent: 'prd' → 'create-prd'
- PM agent: 'gdd' → 'create-gdd'
- New: 'create-epics-and-stories'
- New: 'validate-prd'

## Impact

This update significantly improves the BMM module's ability to:
- Adapt to different project types and scales
- Guide users through discovery naturally vs mechanically
- Generate higher quality planning documents
- Support complex domains with specialized knowledge
- Scale from Level 0 quick changes to Level 4 enterprise projects

The workflows now feel like collaborative discovery sessions with an expert consultant rather than form-filling exercises.
