ISO checks exercise N1x firmware and VM kernel-update bootability

Check the N1x pass against the installed system's detector
Give the N1x pass's VM what Omarchy reads from an N1x's firmware
Install test: build aarch64 from the edge channel's packages
Keep the VM image bootable through the firmware after a kernel update
Merge pull request #293 from omacom/vm-image/keep-limine-default-after-reseal

emirb committed stronger ARM installation checks on quattro. omacom/omarchy-iso@d2a0d47ed320 explains that earlier N1x checks could pass without exercising the installed system's N1x configuration. omacom/omarchy-iso@6edcc58cbf60 supplies the VM with the firmware signals Omarchy actually detects, rather than replacing its detector. ARM installation tests also switched to published edge packages.

A separate VM-image fix removes the build machine's identity from the Limine entry so clones update that entry correctly after kernel changes. emirb reported that the expanded checks failed on the published 4.0.5 image and passed after resealing with the change in omacom/omarchy-iso@bcc340933978. Its merge into quattro is recorded by omacom/omarchy-iso@fd1c9a549a9f; this is development-branch work.
