Configured Ghostty move_tab shortcuts do not reorder tabs

[davdroman]

What happened?

Ghostty keybindings for move_tab:-1 and move_tab:1 have no effect in Supacode. The same Ghostty configuration works in Ghostty, and other configured Ghostty shortcuts work in Supacode.

The expected behavior is for the invoking tab to move left or right, wrapping at the ends according to the Ghostty move_tab contract.

Investigation found that GhosttySurfaceBridge dispatches GHOSTTY_ACTION_MOVE_TAB through onMoveTab, but Supacode never assigns that callback when wiring a terminal surface. The action therefore returns false without changing tab order.

Candidate fix branch: https://github.com/davdroman/supacode/tree/fix/ghostty-tab-move-shortcut

Steps to reproduce

1. Configure Ghostty with keybind = ctrl+cmd+left_bracket=move_tab:-1 and keybind = ctrl+cmd+right_bracket=move_tab:1.
2. Open at least two terminal tabs in Supacode.
3. Focus a terminal and press Command-Control-[ or Command-Control-].
4. Observe that the tabs remain in the same order.
