### Summary

Screenshot editor does not close on Enter in the default Omarchy screenshot flow. After taking a screenshot and opening the annotation editor, pressing Enter copies + saves the annotated image but the editor window stays open — it only closes with Escape. It reads as a "stuck" editor.

### Steps to reproduce

1. Run `omarchy screenshot` (default `slurp` mode) or the screenshot keybind.
2. The notification "Screenshot saved to clipboard and file — Edit with Super + Alt + ," appears. Click it (or press `Super + Alt + ,`) to open the editor.
3. Annotate (add an arrow/box/text, etc.).
4. Press **Enter** (the natural "I'm done" gesture).

**Actual:** the image is copied to the clipboard and written to the screenshot file, but the editor window remains open. It does not close.

**Expected:** Enter closes the editor after saving, matching the previous system's satty editor behavior ("save and close on Enter").

### Root cause

Omarchy's capture script defaults the editor to `$OMARCHY_SCREENSHOT_EDITOR` = `tensaku-edit` (see `/usr/share/omarchy/bin/omarchy-capture-screenshot`). The shipped `/usr/bin/tensaku-edit` wrapper (owned by the `tensaku` package) is invoked with only the image path, so it supplies the flags itself:

```bash
exec tensaku \
  --filename "$1" \
  --output-filename "$1" \
  --actions-on-enter save-to-clipboard \
  --save-after-copy \
  --copy-command wl-copy
```

Note: **no `--early-exit`**. In Tensaku, `--early-exit` is documented as "Exit directly after copy/save action." Without it, Enter copies + saves but deliberately keeps the editor open for continued annotation. This is a behavior mismatch with the satty editor that Omarchy previously used, which the wrapper's own header comment claims it is supposed to match.

### Suggested fix

Add `--early-exit` to the tensaku wrapper so Enter closes the editor after copying/saving, e.g.:

```bash
exec tensaku \
  --filename "$1" \
  --output-filename "$1" \
  --actions-on-enter save-to-clipboard \
  --save-after-copy \
  --copy-command wl-copy \
  --early-exit
```

Since `/usr/bin/tensaku-edit` ships with the `tensaku` package, this either needs to be coordinated with the Tensaku maintainer or Omarchy should set `$OMARCHY_SCREENSHOT_EDITOR` to a wrapper it owns that adds `--early-exit`.

### Notes / severity

- **Low severity.** Nothing is lost today: the base screenshot is already saved to disk and the clipboard before the editor opens; the editor is optional annotation. Escape closes it.
- This is a UX/behavior regression from the earlier satty editor, not a crash or data-loss bug.
- `omarchy debug` is listed under `omarchy --help` in 4.0.0-1 but returns "Unknown Omarchy command" when run, so I couldn't attach a full debug log. Reproducing is straightforward.

### Environment

- Omarchy `4.0.0-1`
- tensaku `0.26.6-1`
- Session: Wayland / Hyprland
- Default editor resolution: `OMARCHY_SCREENSHOT_EDITOR` unset → falls back to `tensaku-edit`
