fix quoting issue

scripts/dev_commands.py

@@ -7,6 +7,11 @@ Design goals:
 - Explicit argv execution throughout.
 - Where practical, allow forwarding extra arguments to underlying tools.
 - Keep Windows/MSVC "one-liner" behavior via cmd.exe only when required.
+
+NOTE (Windows quoting):
+cmd.exe has special/quirky parsing rules for /c when the command contains quotes.
+We use: cmd.exe /d /s /c ""call "<bat>" <arch> && <then...>""
+The doubled quotes at both ends are intentional and required for robust behavior.
