Update Mermaid dependency to v11.14.0+ to enable TreeView diagram support

Proposal

Upgrade the bundled Mermaid dependency to version 11.14.0 or later.

This update would enable:

  • Native TreeView Diagrams: Replace manual ASCII art with concise, renderable Mermaid syntax.
  • Improved Maintainability: No more manual alignment of pipes (|) and dashes (-).
  • Visual Consistency: Diagrams that match GitLab's native styling and support themes (dark/light mode).
  • Access to additional icons: Who doesn't like more icon choices?

Current ASCII Limitation

Currently, I must use pre-formatted text blocks with inconsistent connectors that are prone to misalignment:

my-project/
+-- src/
|   +-- components/
|   |   +-- Header.js
|   |   +-- Footer.js
|   +-- utils/
|   |   +-- helpers.js
|   +-- App.js
+-- public/
|   +-- index.html
|   +-- styles.css
+-- package.json
+-- README.md
+-- tests/
    +-- unit/
    |   +-- components.test.js
    +-- integration/
        +-- api.test.js

Desired State (Mermaid TreeView)

With Mermaid v11.14.0+, I could use clean, indentation-based syntax:

my-project/
    src/
        components/
            Header.js
            Footer.js
        utils/
            helpers.js
        App.js
    public/
        index.html
        styles.css
    package.json
    README.md
    tests/
        unit/
            components.test.js
        integration/
            api.test.js
