fix: add shell=True to launch handler for Windows app resolution

abrichr · claude · abrichr · commit 1f5eb211c10e · 2026-03-21T23:55:05.000-04:00
subprocess.Popen('calc') without shell=True fails on Windows because
CreateProcessW doesn't search PATH the same way cmd.exe does. WAA's
native /setup/launch endpoint hardcodes shell=True which is why it
works. Match that behavior.
