Subject: [PATCH] fix(tui): make hotkeys and numpad work again in IDE while
 focus is in TUI

VS Code's terminal does not support the Kitty keyboard protocol
(microsoft/vscode#286809 was closed), so enabling it has no benefit
and triggers a shortcut dispatch bug where IDE keybindings like
Cmd+Shift+E and Ctrl+Shift+G stop forwarding while the TUI has focus
(microsoft/vscode#304806).

It also triggers a Chromium regression where numpad keys are reported
as "Unidentified" when Kitty protocol is active, causing them to be
silently dropped (microsoft/vscode#299374).

Detect VS Code's terminal via TERM_PROGRAM=vscode (also set by Cursor
and Windsurf) and pass false to useKittyKeyboard to prevent the
protocol from being activated. No functionality is lost since VS Code's
terminal never supported Kitty to begin with.

Fixes #27006
Fixes #16100
