## What happened

`omarchy-menu.jsonc` guards the "Set default editor → Sublime Text" entry with:

```
"setup.default.editor.sublime": {"when":"omarchy-cmd-present sublime_text", ...}
```

and `omarchy-launch-editor` re-validates the stored choice the same way:

```bash
omarchy-cmd-present "$editor" || editor="nvim"
```

Both checks resolve to `command -v sublime_text`. But the `sublime-text-4` Arch package only ships a `subl` wrapper on `PATH` (`/usr/bin/subl`, which execs `/opt/sublime_text/sublime_text`) — nothing named `sublime_text` is ever placed on `PATH`.

Consequences on a stock install (`sublime-text-4` from the official repos):
- The "Sublime Text" default-editor option never appears as *checked*/selectable in the SUPER+SPACE → default editor menu, because the `when` guard is always false.
- Forcing it from the CLI (`omarchy default editor sublime_text`) writes the state file correctly, but `omarchy-launch-editor` still silently falls back to `nvim` on every launch, because its own `omarchy-cmd-present sublime_text` check also fails.

Note: the "Install → Editor → Sublime Text" menu action itself is unaffected, since it launches via `gtk-launch sublime_text` (resolved through the `.desktop` id, not `PATH`) — only the guard/fallback commands that do `command -v sublime_text` are broken.

## Expected

Selecting Sublime Text as the default editor (after installing it, however it was installed) should make `omarchy-launch-editor` actually launch it, and the menu should show it as an available/checked option.

## Steps to reproduce

1. `sudo pacman -S sublime-text-4` (or install via the Omarchy menu's "Install → Editor → Sublime Text").
2. Open the SUPER+SPACE menu → Setup → Default → Editor. Sublime Text is not offered / never shows as checked.
3. `omarchy default editor sublime_text` from a terminal.
4. `omarchy-launch-editor ~/somefile.txt` (or SUPER+SHIFT+N) → opens in Neovim instead of Sublime Text.

## Workaround

Symlinking a `sublime_text` shim onto `PATH` (e.g. `~/.local/bin/sublime_text -> /opt/sublime_text/sublime_text`) makes both the guard and the fallback check pass.
