The exe links MSYS2 mingw64 DLLs (SDL2, libgcc, libstdc++, libwinpthread,
zlib). Run from a normal PowerShell those aren't on PATH, so gdb reported
"During startup program exited with code 0xc0000135" and nothing ran.
Prepend the mingw64 bin dir (derived from -Gdb) to PATH before launching.
Also relax ErrorActionPreference around the gdb call so its stderr
progress lines don't raise NativeCommandError noise mid-run.
