Linux guest image v0.3.1

Guest image for Try Omarchy for Linux 0.3.1. The Linux app downloads this image on first run and when it updates an existing VM.

The app verifies every file against SHA256SUMS, and pins the SHA256 of SHA256SUMS itself:

Changes since linux-v0.3.0 (compatibility revision 66):

• Omarchy's shell keeps its colors with Qt 6.12, including the menu and power panel that show Linux host wording. Runtime 4.0.4-8 carries the fix through later updates.
• Update > Omarchy no longer stops at Omarchy's Snapper migration; the ext4 guest has no Snapper or Limine.
• The guest reports a busy desktop while a package update runs, so the launcher does not offer a restart that would interrupt it.
• Large images from the clipboard arrive without stalling.
• The factory image grows to 8 GiB, and the package lock is refreshed (Qt 6.12, Quickshell 0.3.2, Linux 7.2.11).

Existing VMs receive these through the compatibility overlay on their next start with the new app.
