Greptile Summary

This PR fixes a critical path issue in the GitHub Actions workflow for the Claude NL suite. The change updates the Unity MCP server path from UnityMcpServer/src/server.py to UnityMcpBridge/UnityMcpServer~/src/server.py in the workflow configuration.

The fix addresses the actual Unity package structure where the Python MCP server is located within the UnityMcpBridge package directory. The UnityMcpServer~ subdirectory follows Unity's convention of using the tilde suffix for hidden/special directories that contain implementation details not directly exposed to Unity's asset system.

This change ensures the GitHub Actions workflow can properly locate and start the MCP server when running automated tests. The correction aligns the workflow configuration with the established codebase structure, where the UnityMcpBridge acts as the main Unity package container and houses the Python server implementation in the nested subdirectory.

Bug: Dependency Path Mismatch Causes Installation Failure

The MCP server path was updated to UnityMcpBridge/UnityMcpServer~/src/server.py, but the earlier dependency installation step still looks for requirements.txt at UnityMcpServer/requirements.txt. This inconsistency means dependencies may not be installed, potentially causing the MCP server to fail.
