✨ feat: Add subfolder support for model specs (#9165)

- Add optional `folder` field to TModelSpec type and schema
- Create ModelSpecFolder component for hierarchical display
- Implement expand/collapse functionality for folders
- Update search results to show folder context
- Sort folders alphabetically and specs by order/label
- Maintain backward compatibility (specs without folders appear at root)

This enhancement allows organizing model specs into categories/folders
for better organization and improved user experience when dealing with
many model configurations.

+# Model Spec Subfolder Support
+
+This enhancement adds the ability to organize model specs into subfolders/categories for better organization and user experience.
+
+## Feature Overview
+
+Model specs can now be grouped into folders by adding an optional `folder` field to each spec. This helps organize related models together, making it easier for users to find and select the appropriate model for their needs.
+
+## Configuration
+
+### Basic Usage
+
+Add a `folder` field to any model spec in your `librechat.yaml`:
+
+```yaml
+modelSpecs:
+  list:
+    - name: "gpt4_turbo"
+      label: "GPT-4 Turbo"
+      folder: "OpenAI Models"  # This spec will appear under "OpenAI Models" folder
+      preset:
+        endpoint: "openAI"
+        model: "gpt-4-turbo-preview"
+```
+
+### Folder Structure
+
+- **With Folder**: Model specs with the `folder` field will be grouped under that folder name
+- **Without Folder**: Model specs without the `folder` field appear at the root level
+- **Multiple Folders**: You can create as many folders as needed to organize your models
+- **Alphabetical Sorting**: Folders are sorted alphabetically, and specs within folders are sorted by their `order` field or label
+
+### Example Configuration
+
+```yaml
+modelSpecs:
+  list:
+    # OpenAI Models Category
+    - name: "gpt4_turbo"
+      label: "GPT-4 Turbo"
+      folder: "OpenAI Models"
+      preset:
+        endpoint: "openAI"
+        model: "gpt-4-turbo-preview"
+      
+    - name: "gpt35_turbo"
+      label: "GPT-3.5 Turbo"
+      folder: "OpenAI Models"
+      preset:
+        endpoint: "openAI"
+        model: "gpt-3.5-turbo"
+    
+    # Anthropic Models Category
+    - name: "claude3_opus"
+      label: "Claude 3 Opus"
+      folder: "Anthropic Models"
+      preset:
+        endpoint: "anthropic"
+        model: "claude-3-opus-20240229"
+    
+    # Root level model (no folder)
+    - name: "quick_chat"
+      label: "Quick Chat"
+      preset:
+        endpoint: "openAI"
+        model: "gpt-3.5-turbo"
+```
+
+## UI Features
+
+### Folder Display
+- Folders are displayed with expand/collapse functionality
+- Folder icons change between open/closed states
+- Indentation shows the hierarchy clearly
+
+### Search Integration
+- When searching for models, the folder path is shown for context
+- Search works across all models regardless of folder structure
+
+### User Experience
+- Folders start expanded by default for easy access
+- Click on folder header to expand/collapse
+- Selected model is highlighted with a checkmark
+- Folder state is preserved during the session
+
+## Benefits
+
+1. **Better Organization**: Group related models together (e.g., by provider, capability, or use case)
+2. **Improved Navigation**: Users can quickly find models in organized categories
+3. **Scalability**: Handles large numbers of model specs without overwhelming the UI
+4. **Backward Compatible**: Existing configurations without folders continue to work
+5. **Flexible Structure**: Mix foldered and non-foldered specs as needed
+
+## Use Cases
+
+### By Provider
+```yaml
+folder: "OpenAI Models"
+folder: "Anthropic Models"
+folder: "Google Models"
+```
+
+### By Capability
+```yaml
+folder: "Vision Models"
+folder: "Code Models"
+folder: "Creative Writing"
+```
+
+### By Performance Tier
+```yaml
+folder: "Premium Models"
+folder: "Standard Models"
+folder: "Budget Models"
+```
+
+### By Department/Team
+```yaml
+folder: "Engineering Team"
+folder: "Marketing Team"
+folder: "Research Team"
+```
+
+## Implementation Details
+
+### Type Changes
+- Added optional `folder?: string` field to `TModelSpec` type
+- Updated `tModelSpecSchema` to include the folder field validation
+
+### Components
+- Created `ModelSpecFolder` component for rendering folder structure
+- Updated `ModelSelector` to use folder-aware rendering
+- Enhanced search results to show folder context
+
+### Behavior
+- Folders are collapsible with state management
+- Models are sorted within folders by order/label
+- Root-level models appear after all folders
+
+## Migration
+
+No migration needed - the feature is fully backward compatible. Existing model specs without the `folder` field will continue to work and appear at the root level.
