Hover styles broken on Windows touchscreen PCs due to `@media (hover: hover)` gating in Codex VS Code Extension

What issue are you seeing?

On Windows 11 touchscreen laptops / 2-in-1s (hybrid input), no hover feedback is shown for Codex buttons / controls inside the VS Code WebView.

Situation: Context file "chip" buttons do not darken on hover and their inner remove icon (✕) never appears.

The screenshot above is taken on a Windows Touchscreen PC, where hover rules failed to work even when activated :hover state.

1. Parent file context button --> governed by .hover:bg-token-menu-background:hover and .hover:bg-token-menu-background/60:hover (background color change only).
2. Inner remove button (✕) --> governed by .group-hover:opacity-100:is(:where(.group):hover *) (becomes visible on hover via opacity: 1).

What DevTools shows (from VS Code: Help -> Toggle Developer Tools -> ELements -> Styles):

@media (hover: hover) {
  /* (1) Parent file button: hover only changes background color */
  .hover\:bg-token-menu-background:hover,
  .hover\:bg-token-menu-background\/60:hover {
    background-color: var(--color-token-menu-background);
  }

  /* (2) Inner remove button (✕): only visible when parent (.group) is hovered */
  .group-hover\:opacity-100:is(:where(.group):hover *) {
    opacity: 1;
  }
}

On hybrid devices, @media (hover: hover) evaluates to false because it checks the primary input (often touch). Therefore the hover utilities are never applied even when using a mouse / touchpad.

What steps can reproduce the bug?

1. Open Codex in VS Code on a Windows 11 touchscreen laptop / 2-in-1 with a mouse/trackpad attached.
2. Hover the pointer over any interactive control (e.g., a file chip with a trailing remove icon).
3. Observe: no visual hover feedback; the inner remove icon never becomes visible.
4. Open VS Code -> Help -> Toggle Developer Tools -> Elements -> Styles; observe hover utilities gated by @media (hover: hover)

What is the expected behavior?

• When hovering with a mouse/touchpad on a Windows touchscreen PC, buttons should darken and the inner remove icon should become visible (.group-hover:opacity-100).
• Keyboard focus styles (:focus-visible) and pressed feedback (:active) remain visible.
