### System details

Lenovo ThinkPad P52s (dual battery: internal BAT0 + external BAT1), Intel i5-8350U, Intel UHD 620 + NVIDIA Quadro P500, Omarchy 4.0.3-1, Quickshell 0.3.1

### What's wrong?

On a laptop with two batteries, the power panel (`omarchy.power`) shows contradictory numbers because `omarchy-battery-status` only ever looks at the first battery, while the bar icon and the panel's progress bar use UPower's composite `DisplayDevice`.

`bin/omarchy-battery-status`:

```bash
battery=$(upower -e 2>/dev/null | grep BAT | head -n 1)   # -> battery_BAT0 only
...
cycles=$(cat "$power_supply_path"/BAT*/cycle_count 2>/dev/null | head -1)
```

So in `panels/power/Panel.qml` the hero percentage (`root.batteryInfo.percentage`), "Battery size", "Time to full" and the charge rate all describe BAT0 alone, but `batteryFraction` / `batteryIcon()` (and the bar icon) are computed from `UPower.displayDevice`, which sums both packs.

**Observed** (BAT0 held at its 75–80% charge threshold, BAT1 charging):

| Source | Value |
|---|---|
| `upower -i .../battery_BAT0` | 80%, fully-charged, 31 Wh |
| `upower -i .../battery_BAT1` | 39%, charging, 67 Wh, 31 W, 1.2 h to full |
| `upower -i .../DisplayDevice` | 52%, charging, 98 Wh, 31 W, 1.4 h to full |
| Bar icon | ~52% (composite) ✔ |
| Panel hero number | **80%** (BAT0 only) |
| Panel progress bar | **52%** (composite) — disagrees with the number right above it |
| Panel "Battery size" | **31 Wh** (BAT0 only; machine has 98 Wh) |
| Panel "Time to full" / rate | **—** / **0 W** (BAT0 is idle at its threshold; BAT1 is actually charging at 31 W) |

`omarchy-battery-status --shell` output:

```
percentage	80%
state	holding
rate	0W
size	31Wh
time	
cycles	21
threshold	75-80%
```

**Expected:** the panel should either describe the composite battery (matching the icon and progress bar it already draws from `UPower.displayDevice`), and/or list each pack separately.

**Steps to reproduce:** open the power panel on any dual-battery ThinkPad (T4x0/T4x0s/P5x s-series, X1 Carbon w/ external pack, etc.) with the two packs at different charge levels.

**Suggested fix:** in `omarchy-battery-status`, read the `DisplayDevice` (`upower -i /org/freedesktop/UPower/devices/DisplayDevice`) instead of the first `BAT*` for percentage / size / time / rate, and sum `power_now` across all `BAT*` for the instantaneous rate. `Panel.qml` could also drop the script's percentage and use `Math.round(batteryFraction * 100)` so the hero number can never disagree with the bar beneath it. Happy to send a PR if that direction sounds right.

I worked around it locally by cloning the plugin, using `UPower.displayDevice` for the hero/stats and adding a per-pack list from `UPower.devices` (before/after screenshots attached).
