feat: Streamline settings and document addon support strategy

## 1. Eliminate Unnecessary Settings Tabs ✅

**Before:** 13 tabs (too many!)
**After:** 9 tabs (clean, focused)

**Removed:**
- ❌ Advanced (just redirected to WC Admin)
- ❌ Integrations (just redirected to WC Admin)
- ❌ System Status (just redirected to WC Admin)
- ❌ Extensions (just redirected to WC Admin)

**Kept:**
- ✅ WooNooW (main settings)
- ✅ Store Details
- ✅ Payments (simplified WC UI)
- ✅ Shipping & Delivery (simplified WC UI)
- ✅ Tax (simplified WC UI)
- ✅ Checkout
- ✅ Customer Accounts
- ✅ Notifications
- ✅ Brand & Appearance

**Rationale:**
- Bridge tabs add clutter without value
- Users can access WC settings from WC menu
- Keep only WooNooW simplified UI
- Match Shopify/marketplace patterns

## 2. Settings Pages Implementation Plan ✅

Created SETTINGS_PAGES_PLAN.md with detailed specs for 4 missing pages:

### A. WooNooW Settings
- General settings (SPA mode, theme, items per page)
- Performance (caching, preload)
- Features (quick edit, bulk actions, shortcuts)
- Developer (debug mode, API logs)

### B. Checkout Settings
- Checkout options (guest checkout, account creation)
- Checkout fields (company, address, phone)
- Terms & conditions
- Order processing (default status, auto-complete)

### C. Customer Accounts Settings
- Account creation (registration, username/password generation)
- Account security (strong passwords, 2FA)
- Privacy (data removal, export, retention)
- Account dashboard (orders, downloads, addresses)

### D. Brand & Appearance Settings
- Store identity (logo, icon, tagline)
- Brand colors (primary, secondary, accent)
- Typography (fonts, sizes)
- Admin UI (sidebar, breadcrumbs, compact mode)
- Custom CSS

**Timeline:** 3 weeks
**Priority:** High (WooNooW, Checkout), Medium (Customers), Low (Brand)

## 3. Community Addon Support Strategy ✅

Updated PROJECT_BRIEF.md with three-tier addon support model:

### **Tier A: Automatic Integration** ✅
- Addons respecting WooCommerce bone work automatically
- Payment gateways extending WC_Payment_Gateway
- Shipping methods extending WC_Shipping_Method
- HPOS-compatible plugins
- **Result:** Zero configuration needed

### **Tier B: Bridge Snippets** 🌉
- For addons with custom injection
- Provide bridge code snippets
- Community-contributed bridges
- Documentation and examples
- **Philosophy:** Help users leverage ALL WC addons

### **Tier C: Essential WooNooW Addons** ⚡
- Build only critical/essential features
- Indonesia Shipping, Advanced Reports, etc.
- NOT rebuilding generic features
- **Goal:** Save energy, focus on core

**Key Principle:**
> "We use WooCommerce, not PremiumNooW as WooCommerce Alternative. We must take the irreplaceable strength of the WooCommerce community."

**Benefits:**
- Leverage 10,000+ WooCommerce plugins
- Avoid rebuilding everything
- Focus on core experience
- No vendor lock-in

## Summary

**Settings:** 13 tabs → 9 tabs (cleaner, focused)
**Plan:** Detailed implementation for 4 missing pages
**Strategy:** Three-tier addon support (auto, bridge, essential)

**Philosophy:** Simplify, leverage ecosystem, build only essentials.
