Add configurable feature management system with JSON-based feature flags

Implement comprehensive feature toggle system allowing menu options and features
to be controlled via JSON configuration fetched from API endpoint or static files.

Core System:
- Create FeatureConfig type system with page, feature, and limit-based flags
- Add React Context (FeatureProvider) that fetches from /api/user/features
- Implement custom hooks (useFeatures, useIsFeatureEnabled, useFeatureLimit, etc.)
- Default config disables everything except home page

Integration:
- Update PageHeader to filter menu items based on page flags
- Add ProtectedRoute component to guard routes
- Update VR menu to conditionally render items based on feature flags
- Update CreateDiagramModal to enable/disable options (private, encrypted, invite)
- Update ManageDiagramsModal to use configurable maxDiagrams limit

Configuration Files:
- Add static JSON files for local testing (none, free, basic, pro tiers)
- Add dev proxy for /api/user/features endpoint
- Include README with testing instructions

Updates:
- Complete CLAUDE.md naming conventions section
- Version bump to 0.0.8-27

-- document the toolId and material naming conventions.
+
+## Naming Conventions
+
+### Tool and Material Naming
+
+**Material Names:** Materials follow the pattern `material-{color}` where `{color}` is the hex color string (e.g., `material-#ff0000` for red).
+
+**Tool Mesh Names:** Tools use the pattern `tool-{toolType}-{color}`:
+- Example: `tool-BOX-#ff0000` (red box tool)
+- ToolTypes: `BOX`, `SPHERE`, `CYLINDER`, `CONE`, `PLANE`, `PERSON`
+
+**Tool Instance Names:** `tool-instance-{toolType}-{color}` (e.g., `tool-instance-BOX-#ff0000`)
+
+**Implementation details:**
+- 16 predefined toolbox colors (see docs/NAMING_CONVENTIONS.md)
+- Materials created in `src/toolbox/functions/buildColor.ts`
+- Tool meshes created in `src/toolbox/functions/buildTool.ts`
+- When extracting colors from materials, use: `emissiveColor || diffuseColor` (priority order)
+
+### Rendering Modes
+
+Three rendering modes affect material properties:
+1. **Lightmap with Lighting**: Uses `diffuseColor` + `lightmapTexture` (expensive)
+2. **Unlit with Emissive Texture** (default): Uses `emissiveColor` + `emissiveTexture` (lightmap)
+3. **Flat Emissive**: Uses only `emissiveColor` (fastest)
+
+See `src/util/renderingMode.ts` and `src/util/lightmapGenerator.ts` for implementation.

+# Feature Configuration Testing
+
+This directory contains static JSON files for testing different user tiers locally.
+
+## Available Configurations
+
+### Default: `features` (none tier)
+- **What you see**: Only the home page
+- **All pages and features**: Disabled
+- **Use case**: Unauthenticated users or when API is unavailable
+
+### Free Tier: `features-free.json`
+- **Pages**: All marketing pages + VR Experience
+- **Features**: Basic diagram creation, management, immersive mode
+- **Limits**: 6 diagrams max, 100MB storage
+- **No access to**: Templates, private/encrypted designs, collaboration
+
+### Basic Tier: `features-basic.json`
+- **Pages**: All pages available
+- **Features**: Free features + templates + private designs
+- **Limits**: 25 diagrams max, 500MB storage
+- **No access to**: Encrypted designs, collaboration
+
+### Pro Tier: `features-pro.json`
+- **Pages**: All pages available
+- **Features**: Everything unlocked
+- **Limits**: Unlimited (indicated by -1)
+
+## How to Test Locally
+
+### Method 1: Copy the file you want to test
+```bash
+# Test free tier
+cp public/api/user/features-free.json public/api/user/features
+
+# Test basic tier
+cp public/api/user/features-basic.json public/api/user/features
+
+# Test pro tier
+cp public/api/user/features-pro.json public/api/user/features
+
+# Test none/default (locked down)
+cp public/api/user/features-none.json public/api/user/features
+```
+
+### Method 2: Symlink (easier for switching)
+```bash
+# Remove the default file
+rm public/api/user/features
+
+# Create a symlink to the tier you want to test
+ln -s features-free.json public/api/user/features
+# or
+ln -s features-basic.json public/api/user/features
+# or
+ln -s features-pro.json public/api/user/features
+```
+
+## What Changes Between Tiers
+
+| Feature | None | Free | Basic | Pro |
+|---------|------|------|-------|-----|
+| Pages (Examples, Docs, Pricing) | ❌ | ✅ | ✅ | ✅ |
+| VR Experience | ❌ | ✅ | ✅ | ✅ |
+| Create Diagram | ❌ | ✅ | ✅ | ✅ |
+| Create From Template | ❌ | ❌ | ✅ | ✅ |
+| Private Designs | ❌ | ❌ | ✅ | ✅ |
+| Encrypted Designs | ❌ | ❌ | ❌ | ✅ |
+| Share/Collaborate | ❌ | ❌ | ❌ | ✅ |
+| Max Diagrams | 0 | 6 | 25 | ∞ |
+| Storage | 0 | 100MB | 500MB | ∞ |
+
+## Backend Implementation (Future)
+
+When you're ready to implement the backend, create an endpoint at:
+```
+GET https://www.deepdiagram.com/api/user/features
+```
+
+The endpoint should:
+1. Validate the Auth0 JWT token from `Authorization: Bearer <token>` header
+2. Query the user's subscription tier from your database
+3. Return JSON matching one of these structures based on their tier
+4. Handle errors gracefully (401 for invalid token, 403 for unauthorized)
+
+The frontend will automatically fall back to the static `features` file if:
+- User is not authenticated
+- API returns an error
+- Network request fails
