feat: Add blog post functionality with Markdown support

- Introduced BlogPostNode to render blog posts with metadata and content.
- Updated graph.json to include new blog post nodes.
- Enhanced MarkdownRenderer to support code block options for max height.
- Added CSS styles for improved code block scrolling and syntax highlighting.
- Created example blog posts: "Markdown Formatting Test", "Welcome to My Blog", and "Building Interactive Node Graphs".
- Implemented dynamic loading of blog data from blogs.json.
- Updated WorkspaceNavigator to allow smooth panning over blog nodes.

+# Building Interactive Node Graphs
+
+In this post, I'll share some insights on building interactive node-based graph systems for the web.
+
+## Why Node Graphs?
+
+Node graphs are powerful visual programming tools that make complex logic easier to understand and manipulate:
+
+- **Visual Clarity**: See the flow of data and execution at a glance
+- **Modularity**: Each node is a self-contained unit
+- **Flexibility**: Easy to add new node types and behaviors
+
+## The Architecture
+
+The system is built on several key classes:
+
+### NodeBase
+The abstract base class that all nodes inherit from. It defines the blueprint interface:
+
+```javascript
+class NodeBase {
+    static NodeType = "";
+    static BlueprintPure_GetDefaultPins() { }
+    BlueprintNativeEvent_OnRender(article, graphNode, renderCtx) { }
+    async BlueprintCallable_Execute(ctx) { }
+}
+```
+
+### Node Registry
+Automatically registers node types and creates instances based on type strings.
+
+### Execution Context
+Handles the graph traversal and execution flow when nodes are triggered.
+
+## Creating Custom Nodes
+
+To create a new node type:
+
+1. Extend `NodeBase`
+2. Set a unique `NodeType`
+3. Define pins with `BlueprintPure_GetDefaultPins()`
+4. Implement rendering in `BlueprintNativeEvent_OnRender()`
+5. Implement logic in `BlueprintCallable_Execute()`
+
+That's the blueprint system in a nutshell!
