trop[bot] 43bb93908c fix: correct utility process exit code on Windows (#50386)
* fix: correct utility process exit code on Windows

On Windows, process exit codes are 32-bit unsigned integers (DWORD).
When passed from Chromium to Electron as a signed int and then
implicitly converted to uint64_t, values with the high bit set
(e.g., NTSTATUS codes) undergo sign extension, producing incorrect
values.

Cast the exit code to uint32_t before widening to uint64_t to
prevent sign extension and preserve the original Windows exit code.

Fixes #49455
