docs(claude): Phase 0-4 integration for OMS·WMS·ERP project (D5)

Phase 0 Completion (✅ GO → Phase 1):
- D1: OpenAPI 3.0 spec (30 endpoints, 5 roles, audit trails) ✅
- D2: ADR-001 monolithic SPA (7-layer arch, 4-layer components) ✅
- D3: Database schema v1 (11 entity tables, 3NF, audit logs) ✅
- D4: Component taxonomy (65 components, 451 stories, test strategy) ✅
- D5: CLAUDE.md integration (dev commands, validation checklist) ✅

Phase 1-4 Development Guides Added:
- Phase 1 (Week 1-2): Vite scaffold + Storybook + ESLint setup
  * npm create vite, Storybook 7.0 init, folder structure
  * Exit: All devs can build locally, Storybook on port 6006
- Phase 2 (Week 3-4): 30 Primitives, 180 stories, WCAG 2.1 AA
  * Example: ButtonBase component + stories + tests
  * Exit: axe-core 95+, 70% test coverage
- Phase 3 (Week 5-6): 12 Typed + 12 Domain Fields, Pinia stores
  * TextField example, Pinia order store, OpenAPI client generation
  * Exit: 150 integration tests passing
- Phase 4 (Week 7-8): 11 CRUD templates, 116 E2E tests

+# Configure Storybook for Tabler UI theme
+# File: .storybook/preview.ts
+# Add Tabler CSS: https://cdn.jsdelivr.net/npm/@tabler/core@latest/dist/css/tabler.min.css
+```
+
+#### Step 3: Folder Structure

+# Extends: @typescript-eslint/recommended, plugin:vue/vue3-recommended
+# Rules: no-console (dev only), no-any, no-implicit-any
+```
+
+**Exit Criteria**:

+```
+
+**Exit Criteria**:
+- ✅ 11 full CRUD components built (Order, Inventory, Product, Customer, etc.)
+- ✅ 116 E2E tests passing (11 entities × 10-15 scenarios each)

+
+### Component Development Guide
+
+#### Rules (Principle 1-30 Applied)
+
+1. **Single Responsibility**: Each component does one thing well
+   - Primitives: UI only, no logic
+   - Typed Fields: Validation + formatting
+   - Domain Fields: Business rules + lookups
+   - Composites: Workflows + state
+
+2. **Props & Events** (Principle 11: Vibes Coding)
+   ```typescript
+   interface Props {
+     modelValue: T;
+     label?: string;
+     disabled?: boolean;
+     errorMessage?: string;
+   }
+
+   defineEmits<{
+     'update:modelValue': [value: T];
+     blur: [];
+   }>();
+   ```
+
+3. **Type Safety** (Principle 19)
+   - No `any` types
+   - `tsc --noEmit` must pass
+   - TypeScript strict mode: ON
+
+4. **Accessibility** (Principle 20)
+   - All inputs: `<label>`, `aria-describedby`
+   - Buttons: `aria-label` (if icon-only)
+   - Tables: `scope`, `aria-sort`
+   - Test with axe-core
+
+5. **Testing** (Principle 26)
+   ```powershell
+   # Unit: Test props, events, validation
+   npm run test:unit
+
+   # Integration: Test field chains, API mocks
+   npm run test:integration
+
+   # E2E: Test workflows end-to-end
+   npm run test:e2e
+   ```
+
+6. **Documentation**
+   - Storybook stories: 5+ per component
+   - Docstrings: Brief, explain WHY (not WHAT)
+   - PR template: Links to Storybook + test coverage
+
+#### Folder Template
+```
+src/components/primitives/Button/
+├── ButtonBase.vue         # Component
