### System details

- AMD Ryzen 7 255 w/ Radeon 780M Graphics
- Omarchy `4.0.0.r6815.g50d687a-1`
- Hyprland `0.56.2`
- foot `1.28.0`

### What's wrong?

Universal copy/paste (`Super+C` / `Super+V`) does nothing in foot. It works in other apps (browser etc.).

This is **not** the legacy-config case from #13349: `~/.config/foot/foot.ini` already has the current template bindings:

```ini
[key-bindings]
clipboard-copy=Control+Insert Control+Shift+c XF86Copy
primary-paste=none
clipboard-paste=Shift+Insert Control+Shift+v XF86Paste
```

Terminal detection also works: the foot window carries the `terminal*` tag (checked via `hyprctl repl` with `hl.get_active_window().tags`), so `default/hypr/bindings/clipboard.lua` sends `CTRL SHIFT` + `C`/`V` as intended.

**Cause:** the physically held Super is still in the modifier state when the injected chord arrives, so foot sees `Super+Ctrl+Shift+V`. foot only runs a key binding when the modifiers match exactly, so neither `clipboard-copy` nor `clipboard-paste` fires. Apps that ignore the extra Super (browsers) are unaffected. The comment at the top of `clipboard.lua` says sending explicit mods prevents Super merging into the chord, but foot shows it still does.

### Steps to reproduce

1. Open foot with the current template `foot.ini`.
2. Select some text and press `Super+C`, or press `Super+V` with text on the clipboard.
3. Nothing happens.

Repro without a physical keyboard, into a scratch foot window running `read`:

```bash
printf 'PASTE_MARKER' | wl-copy
# with the scratch foot window focused:
hyprctl repl 'hl.dispatch(hl.dsp.send_key_state({ mods = "SUPER CTRL SHIFT", key = "V", state = "down" })); hl.timer(function() hl.dispatch(hl.dsp.send_key_state({ mods = "SUPER CTRL SHIFT", key = "V", state = "up" })) end, { timeout = 50, type = "oneshot" })'
```

- `mods = "CTRL SHIFT"`: the marker gets pasted.
- `mods = "SUPER CTRL SHIFT"`: nothing gets pasted (simulates the held Super).

### Workaround / possible fix

Add the Super-held chords to foot's bindings:

```ini
clipboard-copy=Control+Insert Control+Shift+c Mod4+Control+Shift+c XF86Copy
clipboard-paste=Shift+Insert Control+Shift+v Mod4+Control+Shift+v XF86Paste
```

With this, the simulated case above pastes, and a real `Super+C` / `Super+V` works in a newly opened foot window. The fix could go into the shipped `config/foot/foot.ini` plus a migration (similar to the open PRs for #13349: #13378 / #13446 / #13649).
