VS Code Insiders tunnel service install from non-standard directory
Detects the VS Code CLI (code-insiders / code) being used to install a remote tunnel as a service, run from outside normal application install locations (e.g. the Windows debug folder). Keyed on the tunnel service install behavior and unusual location rather than a specific file path, so renamed or relocated copies still match. Abuse enables covert remote access via Microsoft tunnel infrastructure. Rotation test: still fires if the actor changes the directory, flags order or infrastructure, as long as the binary is run with tunnel + service install outside standard paths.
