fix(examples): improve updateModelContext with structured YAML frontmatter (#271)

* map-server: fix async/await in ontoolresult, remove unused getViewStorageKey

* fix(map-server): improve updateModelContext and fix initialization

- Use structured YAML frontmatter format for model context (like pdf-server)
- Add tool name, altitude, and cleaner data format
- Fix initialization deadlock: app.connect() was inside ontoolresult handler
  which could never fire until connected
- Fix view state persistence: widgetUUID now properly extracted from
  ontoolresult and used to restore persisted camera position
- Server now includes widgetUUID in tool result _meta for widget identification

* fix(pdf-server): use widgetUUID for page persistence

- Add widgetUUID to tool result _meta for widget identification
- Use widgetUUID instead of generated key (pdfUrl+toolId) for localStorage
- Enables reliable page restoration when revisiting PDF widgets

* fix(transcript-server): use structured YAML frontmatter for model context

- Add tool name, listening status, and unsent entry count in frontmatter
- Consistent format with pdf-server and map-server

* update names

* drop bogus altitude

* Update mcp-app.ts
