## What happened

`omarchy toggle bar on` hides the bar, and `omarchy toggle bar off` shows it — the opposite of what the command's own help text (`omarchy toggle bar [toggle|on|off]`) promises.

## Why

`bin/omarchy-toggle-bar` forwards its argument as-is to the generic toggle helper, but the underlying flag is named `bar-off` (negated), not `bar`:

```bash
#!/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}"
```

`omarchy-toggle` (the shared helper) just does `enable`/`disable` on `~/.local/state/omarchy/toggles/<flag-name>` based on the literal `on`/`off` argument:

```bash
case "$ACTION" in
  ...
  on)
    enable
    ;;
  off)
    disable
    ;;
```

So `omarchy toggle bar on` → `omarchy-toggle bar-off on` → **enables** `bar-off` → bar hidden. And `omarchy toggle bar off` → **disables** `bar-off` → bar shown. Bare `omarchy toggle bar` (no argument) is unaffected since it just flips whichever state currently exists.

## Expected

`omarchy toggle bar on` should show the bar, `omarchy toggle bar off` should hide it.

## Fix

`omarchy-toggle-bar` should invert the argument before forwarding it to the negated `bar-off` flag, e.g.:

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

## Steps to reproduce

```bash
omarchy toggle bar off   # bar disappears... but this is "off" so seems correct
omarchy toggle bar on    # bar stays hidden — should have reappeared
```

Confirmed via `hyprctl layers`: with the `bar-off` flag present, the bar's layer surface still exists but is rendered at `y = -26` (pushed entirely above the top edge of a 26px-tall bar), rather than being destroyed — so the effect is a bar that looks "gone" rather than an obvious toggle state.

## Side effect for end users

Because the flag lives in `~/.local/state/omarchy/toggles/bar-off` (not a config file), an accidental bar-off toggle (e.g. a stray keybind) persists across reboots and Omarchy shell restarts, which reads as "my bar disappeared and won't come back" rather than "I toggled it off." Worth a note in the FAQs but the argument-inversion is the actual bug.
