 * (`PIPELINE_SHELL` override → cmd / PowerShell on Windows → sh on POSIX).
 *
 * Used by `{{inputs.X | shellquote}}` placeholder expansion: the same
 * escaping the runner already uses to wrap argv arrays into a shell string,
 * applied consistently to user inputs the YAML author interpolates by hand.
 *
 * Tying this to the actual launching shell rather than `process.platform`
 * matters because POSIX `'foo'\''bar'` and PowerShell `'foo''bar'` are
 * mutually unsafe — picking the wrong one re-opens the injection hole the
 * filter is supposed to close.
