## What happened

The CPU percentage shown by the bar's system stats (consumed by the "Analytics" bar widget, and any other consumer of `omarchy-system-stats` with no arguments) shows huge negative values, e.g. `-873%`, `-579%`.

## Root cause

`/usr/bin/omarchy-system-stats` (no-arg path) parses `top -bn1` output with awk:

```bash
cpu=$(top -bn1 | awk '/^%?Cpu/ {
  gsub(/,/, "")
  for (i = 1; i <= NF; i++) {
    if ($(i + 1) == "id") {
      printf "%.0f%%", 100 - $i
      exit
    }
  }
}')
```

Under locales where `LC_NUMERIC` uses a comma as the decimal separator (e.g. `es_ES.UTF-8`, and most of Europe/Latin America), `top` prints the idle percentage with a comma instead of a period:

```
%Cpu(s):  5,6 us,  3,4 sy,  0,0 ni, 84,3 id,  4,5 wa,  1,1 hi,  1,1 si,  0,0 st
```

The script's `gsub(/,/, "")` strips *every* comma — including the decimal separator — turning `84,3` into `843`. The subsequent `100 - 843` produces a large negative number, which is what gets displayed as the CPU percentage.

## Steps to reproduce

```bash
# with a decimal-comma locale
LC_NUMERIC=es_ES.UTF-8 LANG=es_ES.UTF-8 omarchy-system-stats
# cpu   -8xx%   (varies with actual load)
```

Or just be running Omarchy with `LANG=es_ES.UTF-8` / `LC_NUMERIC=es_ES.UTF-8` (or any other decimal-comma locale) and open the bar's Analytics/system-stats CPU readout.

## Expected

A sane CPU percentage (0-100), independent of locale.

## Suggested fix

Force `LC_NUMERIC=C` for the `top` invocation (or parse more carefully instead of blanket-stripping commas), e.g.:

```bash
cpu=$(LC_NUMERIC=C top -bn1 | awk '/^%?Cpu/ {
  gsub(/,/, "")
  for (i = 1; i <= NF; i++) {
    if ($(i + 1) == "id") {
      printf "%.0f%%", 100 - $i
      exit
    }
  }
}')
```

The `--bar-widget` path in the same script (which reads `/proc/stat` directly via awk) is unaffected, since it doesn't go through `top`'s locale-formatted output.

## System details

- Omarchy version: 4.0.4-1
- Locale: `LANG=es_ES.UTF-8`, `LC_NUMERIC=es_ES.UTF-8`
- Affected file: `/usr/bin/omarchy-system-stats` (no-arg / non `--bar-widget` path)

## Workaround applied locally

Set `LC_NUMERIC=C` globally via Hyprland's `hl.env` (in `~/.config/hypr/envs.lua`), which fixes it for this and any other locale-sensitive command spawned in the session, without touching the packaged script.
