## What happens

The `omarchy.media` bar widget renders as a blank gap: the play/pause glyph draws, but the track label is invisible — even though the MPRIS service has valid metadata.

```
$ omarchy-shell media status
{"hasPlayer":true,"hasMedia":true,"playing":true,"identity":"Spotify",
 "title":"Klepto - Demo","artist":"Ultra Q","album":"My Guardian Angel (Deluxe)", ...}
```

The widget occupies its full width in the bar, so it reads as a broken/empty slot between the neighbouring icons.

## Expected

The now-playing label renders next to the glyph.

## Root cause

`shell/plugins/services/media/BarWidget.qml` puts the label in a 180px `clip: true` Item and drives it with a marquee:

```qml
Item {
  id: scrollClip
  width: Math.min(root.maxLabelWidth, labelText.implicitWidth)   // maxLabelWidth: 180
  clip: true

  Text {
    id: labelText
    text: root.title + (root.artist ? "  ·  " + root.artist : "")

    property bool needsScroll: implicitWidth > scrollClip.width

    NumberAnimation on x {
      running: labelText.needsScroll && !root.popupOpen && !root.bar.vertical
      loops: Animation.Infinite
      duration: Math.max(6000, labelText.implicitWidth * 25)
      from: scrollClip.width          // <-- fully off the RIGHT edge of the clip
      to: -labelText.implicitWidth
      easing.type: Easing.Linear
    }
  }
}
```

`from: scrollClip.width` starts the label fully outside the clip window. When the title is **short enough to fit**, `needsScroll` is false, so the animation never runs — but `x` is left at that off-screen start offset and nothing ever resets it to `0`.

Net effect: **titles that fit are the ones that disappear.** Longer titles scroll and are visible; short ones are pushed out of the clip and render as empty space.

## Reproduce

1. `omarchy bar put omarchy.media --section right`
2. Play anything with an MPRIS-exposing player (Spotify here) whose `"title · artist"` string is narrower than 180px.
3. The widget shows only the glyph; the label area is blank.
4. `omarchy-shell media status` confirms title/artist are present.

## Evidence

Screenshotting the bar region directly (`grim -g "2080,0 420x28"`) over successive frames:

- Six frames, 1s apart: glyph present every frame, label area empty every frame.
- After forcing a reload, the label appears **frozen** at the right edge of the clip window, showing ~3 characters (`Meg` of "Megatron"), identical across 8 frames a second apart — i.e. parked, not animating.

Before/after capture attached.

## Suggested fix

Reset `x` when the label isn't scrolling, e.g. `onNeedsScrollChanged: if (!needsScroll) x = 0`.

Locally I replaced the marquee with a pinned, elided label, which also removes the periods where a scrolling title is off-screen entirely:

```qml
x: 0
width: scrollClip.width
elide: Text.ElideRight
```

The full string remains available in the hover tooltip and the right-click popup card, so nothing is lost.

## System

- Omarchy `4.0.1-1`
- Hyprland `0.56.2`, kernel `7.1.9-arch1-2`, Arch x86_64
- GMKtec NucBox_K12, AMD Ryzen 7 H 255 w/ Radeon 780M
- Two monitors, 2560x1080 + 2560x1440, both scale 1, bar position `top`
- Player: Spotify `1:1.2.96.518-2` (XWayland)

## Note

While confirming the fix I also hit #8555 — `omarchy-shell shell rescanPlugins` was not enough to pick up the change; a full `omarchy restart shell` was required.
