  Render hook for file-tree code blocks
  Alternative to file-tree shortcode's inner content rendering.

  Supported attributes:
  - level: The expand level of the tree (expand all: -1, collapse all: 0, default: 1)
  - folder_slash: Whether to append a trailing "/" to folder names (default: false)
  - ignore_list: List of file or folder names to ignore, separated by commas
  - highlight_list: List of file or folder names to highlight, separated by commas

  Content format: YAML/JSON/TOML with the following item structure:
    name: string     - The name of the file or folder
    type: string     - Type of item, either "dir" (directory) or "file"
    children?: array - (Optional) Array of child items, only valid for directories

  Example usage:
    ```file-tree {level=2 folder_slash=true}
    - name: my-project
      type: dir
      children:
        - name: src
          type: dir
        - name: package.json
          type: file
    ```
