feat(process): wire execute output handling to a callback model

Replace the Option<&mut PhpMixed> output plumbing with the IntoExecOutput
trait modelling each PHP `$output` case (forward, capture-to-buffer,
discard, callback). This lets do_execute pass a real output handler to
Process::run, captures output back via get_output, and lets Svn pass its
streaming filter handler through execute instead of skipping it.
