fix(mcp): parse dependency graph API response correctly

[DevanshuNEU]

Problem

The MCP get_dependency_graph tool was showing 0 files and 0 dependencies because it expected total_files and total_dependencies fields from the API, but the API returns nodes[] and edges[] arrays instead.

Solution

• Parse nodes[] array to get total file count
• Parse edges[] array to calculate critical files by counting dependents
• Show files with most imports from nodes data
• Use metrics.total_edges for total dependencies count

Before

Total Files: 0
Total Dependencies: 0

After

Total Files: 47
Total Dependencies: 34

Most Critical Files:
- src/vanilla.ts - 10 dependents
- tests/test-utils.ts - 2 dependents
- src/middleware/devtools.ts - 2 dependents

Testing

Tested locally with zustand repository - dependency graph now shows correct data.
