Add graph visualizations to anomaly detection

[JohT]

🚀 Feature: Anomaly Detection Graph Visualizations

• Add graph visualizations to anomaly detection: For any of the top 5 anomaly archetypes (Hub, Bottleneck, Authority, Bridge and Outlier), a Graph is visualized showing the focused node and its direct incoming and outgoing dependencies.
• Add anomaly detection Graph visualizations to Markdown summary: The new Graph visualizations are also integrated in the human and large language model readable summary report.
• Add normalized PageRank to ArticleRank difference to features: Additionally to the results of the Page Rank and Article Rank score, their normalized values and their normalized difference value is added to the respective nodes.

⚙️ Optimization

• Support working offline by using local git commands
• Support offline visualization by first installing npm packages locally

🛠 Fix

• Fix unnecessary heading double quote: GraphViz file generation now treats double quotes correctly.
