Agent windows (`org.omarchy.agent`) are excluded from the terminal
`scroll_touchpad` rule, making touchpad scrolling ~10x slower than in a
regular terminal window.

## What happens

`default/hypr/input.lua` speeds up touchpad scrolling per terminal class:

```lua
-- default/hypr/input.lua:82
o.window("(Alacritty|kitty|foot)", { scroll_touchpad = 1.5 })
o.window("com.mitchellh.ghostty", { scroll_touchpad = 0.2 })
```

But `omarchy-agent` deliberately gives every agent window a fixed app-id:

```sh
# /usr/bin/omarchy-agent:111
# A fixed app-id rather than the default org.omarchy.<binary>, so every agent
# window shares one class for window rules and themes to single out.
exec omarchy-launch-tui --app-id=org.omarchy.agent "${command[@]}"
```

`org.omarchy.agent` does not match `(Alacritty|kitty|foot)`, so agent windows
get no `scroll_touchpad` rule at all and fall back to 1.0.

A second factor compounds it. foot only applies its own
`scrollback.multiplier` (7.0 in Omarchy's `config/foot/foot.ini`) when it
scrolls its own scrollback. Once the client enables the alternate screen with
mouse reporting, the multiplier is skipped:

```c
/* foot 1.27.0, input.c:3368 */
static double
mouse_scroll_multiplier(const struct terminal *term, const struct seat *seat)
{
    return (term->grid == &term->normal ||
            (term_mouse_grabbed(term, seat) && term->alt_scrolling))
        ? term->conf->scrollback.multiplier
        : 1.0;
}
```

Agents run a fullscreen TUI, so that is always the case for them.

Combined effect on a touchpad:

| window | window rule | foot multiplier | effective |
|---|---|---|---|
| regular `foot` window | 1.5 | 7.0 | 10.5x |
| `org.omarchy.agent` | 1.0 (no rule) | 1.0 | 1x |

## Steps to reproduce

1. Default terminal set to foot, on a laptop touchpad.
2. Open a regular terminal and run any pager or TUI that scrolls its scrollback.
   Two-finger scroll moves at a normal pace.
3. `Super + Shift + Ctrl + A` to open an agent window, let it produce enough
   output to scroll, and two-finger scroll. It crawls.

## Expected

Touchpad scrolling in an agent window should feel the same as in a regular
terminal window.

## Workaround

```lua
-- ~/.config/hypr/input.lua
o.window("org.omarchy.agent", { scroll_touchpad = 10.0 })
```

10.0 is the maximum Hyprland accepts for `scrolltouchpad`; 10.5 is rejected
with `value 10.50 is more than the maximum of 10.00`.

## Note on a proper fix

Simply adding `org.omarchy.agent` to the existing rule would not be enough —
1.5 only works for windows that also get foot's 7.0 scrollback multiplier,
which a fullscreen TUI never does. Agent windows need roughly the product of
the two (~10).

There is also a wrinkle: because `omarchy-agent` pins one app-id for every
terminal, the class no longer says which terminal is running, while the
existing rules are deliberately per-terminal (0.2 for ghostty vs 1.5 for
foot/alacritty/kitty). A correct fix probably has to pick the value in
`omarchy-agent` / `omarchy-launch-tui` where the terminal is known, rather
than in a class-based window rule.

## System

- Omarchy 4.0.1-2 (`omarchy` and `omarchy-settings` both 4.0.1-2)
- Hyprland on Arch (aarch64, Apple Silicon / Asahi)
- Terminal: foot 1.27.0
- Agent: Claude Code, `tui: fullscreen`
