[PATCH 0/1] MR10594: Draft: vbscript: Log call stack trace on runtime errors.

[Francis De Brabandere (＠francisdb)]

Add WARN-level trace output showing the call chain when a runtime
error propagates through nested function calls. This helps diagnose
errors in ExecuteGlobal/Execute code where the reported error
location has no context about which call chain led to it.

```
Example output for WINEDEBUG=warn+vbscript:
  error 0x80020012 in L"Broken", line 3
    called from L"Wrapper", line 2
    called from <global>, line 16
```
