escapePercentForCmd ran as a post-pass over the quoted string, so it inserted a quote wherever a percent was -- including straight after a backslash. CommandLineToArgvW reads backslash-quote as an escaped quote, so C:\Users\%USERNAME%\x arrived corrupted. That is about as common as Windows paths get, and my 20-case corpus had no backslash-before-percent entry to catch it. Percent handling is now part of the quoting loop, where the backslash run is known and can be doubled before the inserted quote. Two corpus cases cover the shape. The program path gets the same treatment. It was quoted but not percent-escaped, so a launcher under C:\Users\%USERNAME%\ had its own path expanded on the cmd hop. quoteWindowsArgument no longer takes a boolean. Passing it to values.map() handed map's index in as the flag -- which is how the first version of this fix was written, and the corpus test caught it. Separately: an AbortSignal that was already aborted never fires the event, so runProcess ran the child to its full timeout for a caller who had already given up.
