feat: complete monorepo structure with frontend and shared resources

- Add complete backend/ directory with full Django application
- Add frontend/ directory with Vite + TypeScript setup ready for Next.js
- Add comprehensive shared/ directory with:
  - Complete documentation and memory-bank archives
  - Media files and avatars (letters, park/ride images)
  - Deployment scripts and automation tools
  - Shared types and utilities
- Add architecture/ directory with migration guides
- Configure pnpm workspace for monorepo development
- Update .gitignore to exclude .django_tailwind_cli/ build artifacts
- Preserve all historical documentation in shared/docs/memory-bank/
- Set up proper structure for full-stack development with shared resources

+# Search Integration Plan
+
+## 1. File Structure
+```plaintext
+core/
+├── views/
+│   └── search.py          # Search views implementation
+├── utils/
+│   └── search.py          # Search utilities
+templates/
+└── core/
+    └── search/            # Search templates
+        ├── results.html
+        ├── filters.html
+        └── ... 
+```
+
+## 2. View Migration
+- Move `search/views.py` → `core/views/search.py`
+- Update view references:
+```python
+# Old: from search.views import AdaptiveSearchView
+# New:
+from core.views.search import AdaptiveSearchView, FilterFormView
+```
+
+## 3. URL Configuration Updates
+Update `thrillwiki/urls.py`:
+```python
+# Before:
+path("search/", include("search.urls", namespace="search"))
+
+# After:
+path("search/", include("core.urls.search", namespace="search"))
+```
+
+Create `core/urls/search.py`:
+```python
+from django.urls import path
+from core.views.search import AdaptiveSearchView, FilterFormView
+from rides.views import RideSearchView
+
+urlpatterns = [
+    path('parks/', AdaptiveSearchView.as_view(), name='search'),
+    path('parks/filters/', FilterFormView.as_view(), name='filter_form'),
+    path('rides/', RideSearchView.as_view(), name='ride_search'),
+    path('rides/results/', RideSearchView.as_view(), name='ride_search_results'),
+]
+```
+
+## 4. Import Cleanup Strategy
+1. Update all imports:
+```python
+# Before:
+from search.views import ...
+from search.utils import ...
+
+# After:
+from core.views.search import ...
+from core.utils.search import ...
+```
+
+2. Remove old search app:
+```bash
+rm -rf search/
+```
+
+3. Update `INSTALLED_APPS` in `thrillwiki/settings.py`:
+```python
+# Remove 'search' from INSTALLED_APPS
+INSTALLED_APPS = [
+    # ...
+    # 'search',  # REMOVE THIS LINE
+    # ...
+]
+```
+
+## 5. Implementation Steps
+1. Create new directory structure in core
+2. Move view logic to `core/views/search.py`
+3. Create URL config in `core/urls/search.py`
+4. Move templates to `templates/core/search/`
+5. Update all import references
+6. Remove old search app
+7. Test all search functionality:
+   - Park search filters
+   - Ride search
+   - HTMX filter updates
+8. Verify URL routes
+
+## 6. Verification Checklist
+- [ ] All search endpoints respond with 200
+- [ ] Filter forms render correctly
+- [ ] HTMX updates work as expected
+- [ ] No references to old search app in codebase
+- [ ] Templates render with correct context
