fix(cli): quote py interpreter path when it contains whitespace

For the `py` script type, the resolved interpreter may be an absolute
path containing spaces (notably `sys.executable` under Windows
`Program Files`). Quote it when it contains whitespace so the `{SCRIPT}`
invocation isn't split into multiple arguments. Add positive/negative
tests for the quoting behavior.
