## What happened

Running `omarchy install service sunshine` installs the `sunshine` package successfully, but then fails with:

```
Failed to enable unit: Unit sunshine.service does not exist.
```

Because the script (`omarchy-install-service-sunshine`) has `set -e`, it aborts immediately at this step. As a result, everything after the `systemctl --user enable --now sunshine` line never runs:

- The Moonlight UFW firewall rules (LAN + Tailscale) are never opened
- The "Sunshine Admin" web-app shortcut is never installed
- The Hyprland autostart entry is never added

The user is left with Sunshine installed but not reachable from the network and not auto-starting, with only that one error line as feedback.

## Why it happens

The currently packaged `sunshine` (2026.516.143833-4) ships its systemd user unit as:

```
/usr/lib/systemd/user/app-dev.lizardbyte.app.Sunshine.service
```

not `sunshine.service`. The install script hardcodes the old unit name:

```bash
systemctl --user enable --now sunshine
```

which no longer resolves.

## Steps to reproduce

1. On a current Omarchy install, run `omarchy install service sunshine`
2. Package installs fine
3. See the `Failed to enable unit: Unit sunshine.service does not exist.` error and the script stops; no firewall rules, webapp, or autostart entry are created

## Expected

The script enables/starts Sunshine and completes the remaining setup steps (firewall, admin webapp shortcut, autostart).

## Suggested fix

Reference the actual shipped unit name (`app-dev.lizardbyte.app.Sunshine.service`) in `omarchy-install-service-sunshine`, e.g.:

```bash
systemctl --user enable --now app-dev.lizardbyte.app.Sunshine.service
```

or resolve it dynamically instead of hardcoding, in case the upstream unit name changes again. Worth double-checking `omarchy-remove-service-sunshine` too — it calls `systemctl --user disable --now sunshine`, which currently no-ops silently (the failure is swallowed by `|| true`), so uninstall "succeeds" without actually disabling the real unit.

## System details

- Omarchy version: 4.0.2-1
- GPU: AMD Radeon RX 9060 XT (Navi 44, amdgpu driver)
- sunshine package version: 2026.516.143833-4

## Workaround used

Manually enabling the correct unit name and completing the remaining steps from the script by hand got Sunshine fully working (systemd unit active, firewall rules added, admin webapp and autostart configured).
