What happens if the twisted short is grounded as in lightning protection?
Is there any succinct difference?

By how much does the length of the short-circuiting bar at the end of

1/4-wave stub affect its resonant length?

I just twist the ends together. I don't use a bar.

What open-circuit resonant frequency does the stub change to when the
short
circuiting bar is removed?

Same resonant frequency - virtual impedance at the input is reversed.
