feat: add documentation automation system with comprehensive README files

Add `documentation_automation` Django app for automatically generating and maintaining README documentation across the codebase. Generates targeted README files for each module, package, and subdirectory with clear, concise module summaries.

## Changes

- New `apps/documentation_automation` Django app with:
  - `analyzer.py`: Analyzes Python modules and extracts docstrings
  - `detector.py`: Detects modules and their structure
  - `generator.py`: Generates README content from analysis
  - Management command `generate_readmes`: Orchestrates README generation
  - Task support for async README generation
  - Quick start guide

- Generated 180+ README files across the codebase:
  - Core modules (`admin/`, `api/`, `cache/`, `decorators/`, etc.)
  - Django apps (`apps/accounts/`, `apps/changelog/`, `apps/organizations/`, etc.)
  - External library integrations (`lib/google/`, `lib/stripe/`, `lib/slack/`, etc.)
  - Utility modules (`utils/`, `forms/`, `middleware/`, etc.)
  - Test scaffolding (`test_scaffold/`)

- Updated existing README files for:
  - Main project README with documentation structure overview
  - Key module READMEs with comprehensive documentation

- Corrected Hacktoolkit branding to proper capitalization (only H capitalized)

- Updated `.gitignore` to exclude MkDocs build artifacts (`site/`)

+# HTK Admin Module
+
+> Django admin customizations and abstract base classes for consistent admin interfaces.
+
+## Purpose
+
+The admin module provides reusable Django admin classes and decorators to reduce boilerplate when building consistent admin interfaces across multiple models.
+
+## Quick Start
+
+```python
+from django.contrib import admin
+from htk.admin.classes import AbstractAttributeAdmin
+from myapp.models import Product
+
+@admin.register(Product)
+class ProductAdmin(AbstractAttributeAdmin):
+    list_display = ['name', 'price', 'is_active']
+    list_filter = ['is_active', 'created_at']
+    search_fields = ['name', 'description']
+    readonly_fields = ['created_at', 'updated_at']
+```
+
+## Key Components
+
+| Component | Purpose |
+|-----------|---------|
+| **AbstractAttributeAdmin** | Base class for models with dynamic attributes |
+| **admin decorators** | Performance and permission checking decorators |
+| **custom admin site** | Custom AdminSite subclass for branding |
+
+## Common Patterns
+
+### Organized Fieldsets
+
+```python
+@admin.register(User)
+class UserAdmin(AbstractAttributeAdmin):
+    list_display = ['username', 'email', 'is_active']
+    readonly_fields = ['created_at', 'updated_at']
+
+    fieldsets = (
+        ('Account', {'fields': ('username', 'email')}),
+        ('Personal', {'fields': ('first_name', 'last_name')}),
+        ('Permissions', {
+            'fields': ('is_active', 'groups'),
+            'classes': ('collapse',)
+        }),
+    )
+```
+
+### Custom List Display with Formatting
+
+```python
+from django.utils.html import format_html
+
+@admin.register(Product)
+class ProductAdmin(admin.ModelAdmin):
+    list_display = ['name', 'colored_price', 'status_badge']
+
+    def colored_price(self, obj):
+        color = 'green' if obj.price < 100 else 'red'
+        return format_html(
+            '<span style="color: {};">${}</span>',
+            color, obj.price
+        )
+
+    def status_badge(self, obj):
+        return format_html(
+            '<span style="color: {};">●</span> {}',
+            'green' if obj.is_active else 'red',
+            'Active' if obj.is_active else 'Inactive'
+        )
+```
+
+### Inline Admin
+
+```python
+class BookInline(admin.TabularInline):
+    model = Book
+    extra = 1
+
+@admin.register(Author)
+class AuthorAdmin(admin.ModelAdmin):
+    list_display = ['name', 'email']
+    inlines = [BookInline]
+```
+
+### Permission-Based Fields
+
+```python
+@admin.register(SensitiveData)
+class SensitiveDataAdmin(admin.ModelAdmin):
+    def get_fields(self, request, obj=None):
+        fields = ['name', 'description']
+        if request.user.is_superuser:
+            fields.append('api_key')
+        return fields
+
+    def get_readonly_fields(self, request, obj=None):
+        if not request.user.is_superuser:
+            return ['api_key']
+        return []
+```
+
+## Best Practices
+
+- **Organize fields with fieldsets** - Group related fields, use collapse for advanced options
+- **Implement search** - Index searchable fields with `search_fields`
+- **Use list filters** - Provide common filter options
+- **Secure with permissions** - Check `has_change_permission()` and `has_delete_permission()`
+- **Use raw_id_fields** - For large foreign key lists instead of dropdowns
+- **Show key info in list_display** - Balance visibility with performance
+
+## Testing
+
+```python
+from django.test import TestCase
+from django.contrib.admin.sites import AdminSite
+from myapp.models import Product
+from myapp.admin import ProductAdmin
+
+class ProductAdminTestCase(TestCase):
+    def setUp(self):
+        self.admin_site = AdminSite()
+        self.admin = ProductAdmin(Product, self.admin_site)
+
+    def test_list_display(self):
+        """Verify list display fields."""
+        self.assertEqual(
+            self.admin.list_display,
+            ['name', 'price', 'category']
+        )
+```
