docs: update codebase-architecture.md to reflect ansible and tofu module refactoring

- Update Ansible integration section with new template/renderer/ hierarchy
- Update Tofu integration section with new template/renderer/ hierarchy
- Add new 'Recent Architecture Improvements' section documenting the refactoring
- Update module statistics from 79 to 85 files after reorganization
- Explain benefits of hierarchical organization and elimination of redundant naming
- All markdown linting passing

+### Hierarchical Module Organization (September 2024)
+
+Recent refactoring efforts have improved the module organization for both `Ansible` and `OpenTofu` integrations:
+
+**Before:**
+```
+src/ansible/template_renderer.rs
+src/tofu/template_renderer.rs
+src/tofu/cloud_init_template_renderer.rs
+```
+
+**After:**
+```
+src/ansible/template/
+├── mod.rs
+└── renderer/
+    ├── mod.rs (AnsibleTemplateRenderer)
+    └── inventory.rs (InventoryTemplateRenderer)
+
+src/tofu/template/
+├── mod.rs
+└── renderer/
+    ├── mod.rs (TofuTemplateRenderer)
+    └── cloud_init.rs (CloudInitTemplateRenderer)
+```
+
+**Benefits of the New Structure:**
+
+- **Eliminated Redundant Naming**: Removed `_template_renderer` suffixes from file names
+- **Logical Hierarchy**: Clear `template/renderer/` organization pattern
+- **Better Separation**: Specialized renderers properly grouped by functionality
+- **Consistent Pattern**: Same organizational approach across both modules
+- **Improved Maintainability**: Easier to locate and modify specific template renderers
+
+This refactoring maintains full backward compatibility while providing a cleaner, more maintainable codebase structure.
