refactor!: major directory restructuring and npx support

- Create agents/ directory, move bmad, requirements, development-essentials
- Remove docs/, hooks/, dev-workflow/ directories
- Add npx support via github:cexll/myclaude
- Add bin/cli.js with --update command for installed modules
- Add package.json, skills/README.md, PLUGIN_README.md
- Update all references across config.json, README, marketplace.json
- Change default module from dev to do
- Update CHANGELOG with all 59 tags

BREAKING CHANGE: Directory structure changed, docs/hooks removed

+# bmad - BMAD Agile Workflow
+
+Full enterprise agile methodology with 6 specialized agents, UltraThink analysis, and repository-aware development.
+
+## Installation
+
+```bash
+python install.py --module bmad
+```
+
+## Usage
+
+```bash
+/bmad-pilot <PROJECT_DESCRIPTION> [OPTIONS]
+```
+
+### Options
+
+| Option | Description |
+|--------|-------------|
+| `--skip-tests` | Skip QA testing phase |
+| `--direct-dev` | Skip SM planning, go directly to development |
+| `--skip-scan` | Skip initial repository scanning |
+
+## Workflow Phases
+
+| Phase | Agent | Deliverable | Description |
+|-------|-------|-------------|-------------|
+| 0 | Orchestrator | `00-repo-scan.md` | Repository scanning with UltraThink analysis |
+| 1 | Product Owner (PO) | `01-product-requirements.md` | PRD with 90+ quality score required |
+| 2 | Architect | `02-system-architecture.md` | Technical design with 90+ score required |
+| 3 | Scrum Master (SM) | `03-sprint-plan.md` | Sprint backlog with stories and estimates |
+| 4 | Developer | Implementation code | Multi-sprint implementation |
+| 4.5 | Reviewer | `04-dev-reviewed.md` | Code review (Pass/Pass with Risk/Fail) |
+| 5 | QA Engineer | Test suite | Comprehensive testing and validation |
+
+## Agents
+
+| Agent | Role |
+|-------|------|
+| `bmad-orchestrator` | Repository scanning, workflow coordination |
+| `bmad-po` | Requirements gathering, PRD creation |
+| `bmad-architect` | System design, technology decisions |
+| `bmad-sm` | Sprint planning, task breakdown |
+| `bmad-dev` | Code implementation |
+| `bmad-review` | Code review, quality assessment |
+| `bmad-qa` | Testing, validation |
+
+## Approval Gates
+
+Two mandatory stop points require explicit user approval:
+
+1. **After PRD** (Phase 1 → 2): User must approve requirements before architecture
+2. **After Architecture** (Phase 2 → 3): User must approve design before implementation
+

+```
+
+## UltraThink Methodology
+
+Applied throughout the workflow for deep analysis:
+
+1. **Hypothesis Generation** - Form hypotheses about the problem
+2. **Evidence Collection** - Gather evidence from codebase
+3. **Pattern Recognition** - Identify recurring patterns
+4. **Synthesis** - Create comprehensive understanding
+5. **Validation** - Cross-check findings
+
+## Interactive Confirmation Flow
+
+PO and Architect phases use iterative refinement:
+
+1. Agent produces initial draft + quality score
+2. Orchestrator presents to user with clarification questions
+3. User provides responses
+4. Agent refines until quality >= 90
+5. User confirms to save deliverable
+
+## When to Use
+
+- Large multi-sprint features
+- Enterprise projects requiring documentation
+- Team coordination scenarios
+- Projects needing formal approval gates
