From c34c18ec0c472ab1235af7e2b5f267f9b4885a26 Mon Sep 17 00:00:00 2001 From: Willie Ruemmele Date: Wed, 26 Aug 2026 08:41:26 -0600 Subject: [PATCH 1/6] fix: handle spaces in process.execPath on Windows @W-23997746@ Use Node.js's argv0 spawn option to pass a quoted process.execPath into the command line on Windows when the path contains spaces. This separates executable resolution (unquoted path for lpApplicationName) from command-line construction (quoted for correct argv parsing in the child process). Retains windowsVerbatimArguments to preserve the existing security property of preventing argument injection.
