visum_launch_project
Open a Visum project file to enable structured sequential thinking for breaking down complex problems into manageable steps.
Instructions
⚠️ DEPRECATED: Use 'project_open' tool instead. This tool is obsolete and slower than the new TCP-based project_open tool.

Implementation Reference
- src/index-backup.ts:341-417 (handler)The handler function for the 'visum_launch_project' tool. It executes VisumPy code to load a specific Visum project (.ver file), retrieves basic network statistics, and returns formatted success or error messages.
