WezTerm supports sixel but not Kitty graphics. However it appears to respond to the Kitty graphics protocol query in a way that causes misdetection, which previously caused shm segment leaks.

WezTerm sets TERM_PROGRAM=WezTerm, so we can check that and skip the Kitty graphics detection entirely, defaulting to sixel.

I tried the branch fix/7-skip-kitty-for-wezterm, and it corrects both problems for me: There is no memory leak, and the sixel graphics in demos/test_sixel_diag.jl are visible. Thanks!

FYI: I found why Kitty graphics are not working with WezTerm: https://github.com/wezterm/wezterm/issues/7631
