## What happened

Running `omarchy toggle bar on` **hides** the top bar, and `omarchy toggle bar off` **shows** it — the exact opposite of what the command name and its own documented examples imply.

Root cause: `omarchy-toggle-bar` forwards the raw `on`/`off` argument straight through to the underlying `bar-off` flag without inverting it:

```bash
$ cat $(which omarchy-toggle-bar)
#!/bin/bash

# omarchy:summary=Toggle bar visibility without killing the Omarchy shell
# omarchy:args=[toggle|on|off]
# omarchy:examples=omarchy toggle bar | omarchy toggle bar off | omarchy toggle bar on

omarchy-toggle bar-off "${1:-toggle}"
```

Since the underlying flag is named `bar-off` (true = bar is hidden), passing `on` sets `bar-off` to enabled (bar hidden), and passing `off` disables `bar-off` (bar shown). The wrapper needs to invert the action before forwarding it to the `bar-off` flag, e.g. map `on -> off` and `off -> on` (and leave `toggle` as-is).

## How I found it / reproduction

1. On a fresh boot the top bar wasn't rendering at all, even though the `omarchy-shell` (quickshell) process was alive.
2. `hyprctl layers` showed the `omarchy-bar` layer surface existing but positioned off-screen: `xywh: 1920 -26 1920 26` (26px above the visible monitor area, i.e. in its hidden position).
3. `omarchy toggle enabled bar-off` returned exit code `0`, confirming the `bar-off` flag was active (bar hidden).
4. Ran `omarchy toggle bar on` expecting it to show the bar — instead `omarchy toggle enabled bar-off` still returned `0` (still hidden), and the layer stayed at `y: -26`.
5. Ran `omarchy toggle bar off` instead — the `bar-off` flag was cleared (`omarchy toggle enabled bar-off` now returns exit `1`), and `hyprctl layers` immediately showed the bar back at `xywh: 1920 0 1920 26` (visible).

So functionally:
- `omarchy toggle bar on` → bar hidden
- `omarchy toggle bar off` → bar shown

## Expected

- `omarchy toggle bar on` → bar visible
- `omarchy toggle bar off` → bar hidden

matching the command's own summary/examples ("Toggle bar visibility... omarchy toggle bar off | omarchy toggle bar on").

## System details

- Omarchy version: `4.0.0-1`
- Compositor: Hyprland (single laptop panel monitor, `eDP-1`, active at the time of testing)
- `omarchy debug` is not an available command on this version (`omarchy commands --all` has no `debug` entry), so I couldn't attach the standard diagnostic log.

## Suggested fix

In `omarchy-toggle-bar` (or wherever it lives in the source tree), invert the action before forwarding to the `bar-off` flag, e.g.:

```bash
#!/bin/bash
case "${1:-toggle}" in
  on) omarchy-toggle bar-off off ;;
  off) omarchy-toggle bar-off on ;;
  *) omarchy-toggle bar-off toggle ;;
esac
```

Happy to open a PR with this fix if useful.
