[Doc Collector] State transition diagram

[DavertMik]

Doc collector must draw state transition diagram as outcome in Mermaid format

So we collected pages and we must link where we can come from which page
Avoid global navigation or circular references
Use maningful URLs/States (modals too!) and

Example:

Suites page (/suites)
├── Import tests — modal
├── Chat with tests — modal
├── Suite view — /suites/<id>
└── Test view — /test/<id>

Also doc collector must know how to capture modals/screen areas

Notes:

• this can be saved as artifact by other agents
• make links clickable? to open states
• make this diagram as main output of doc collector
• mermaid diagram can be embedded into index.md so we could easily review and navigate over states
