Backspace doesn't work in terminal (-nw) mode

[bleibig]

When running ghostel in emacs terminal mode, the backspace key does not do anything.

I am able to reproduce with these steps on Emacs 30.2:

emacs -q -nw
M-x package-vc-install https://github.com/dakra/ghostel.git
M-x ghostel

And type some text and then backspace.

I've observed from some quick debugging, when backspace is pressed in terminal mode, ghostel--send-event function receives ASCII 127 (^?) from last-command-event and it is not being properly translated to a backspace command. On GUI, that function just receives backspace which is handled properly.

Thanks for the bug report.
Should be fixed on main.
