Leave overlays out of the boot check when update-m1n1's configuration does

[scottjones]

Summary

Two follow-ups to #3. The boot check now leaves device tree overlays out when /etc/default/update-m1n1 doesn't apply them, so it stops failing a boot.bin that update-m1n1 built correctly and blocking omarchy update. That happens with an owner's edited copy that pacman kept over the .pacnew, or with no config file at all. The README also says that changing the opt-in list needs sudo update-m1n1.

 overlays installed?
+  config never calls dtb_overlays_update_m1n1  → warn (merge the .pacnew), leave them out
   DTBS set in the config                       → warn, leave them out
   update-m1n1 default not recognised          → warn, leave them out
   dtc missing or too old                       → warn, leave them out
   else                                         → rebuild with the overlays

The check looks for the call in the file instead of running it, because the config loads the overlay library from an absolute path, which a check of another root can't follow.

Evidence

omarchy-mac-boot/test/apple-silicon-boot-check-test.sh, new cases: an edited config without the call, and no config, each with a boot.bin built without the overlays.

• Before: not ok - an m1n1 image built without the overlays, with the configuration edited passes
• After: passes with the warning; the packaged config still fails that boot.bin as stale. omarchy-mac-boot/test/all passes on an M2 Max (with the snapshot-test fix from Hide the platform detector without hiding /usr/bin in the snapshot check test #9 in place).

Merge Danger

Door: two-way

Blast Radius: edge Macs with overlays

This can happen now. omarchy-mac-boot 20261004-2 (built from #3) and omarchy-ane-dkms 0.4.5 are on edge, and the ANE package ships overlays in /usr/lib/omarchy-mac-boot/dtb-overlays. On a Mac whose owner edited /etc/default/update-m1n1 before upgrading, installing it makes the boot check fail a correct boot.bin and stop omarchy update. The ANE overlays for T6000 and T6020 are opt-in, which is where the README note matters. The change itself only relaxes the check for a config that doesn't apply overlays; with the packaged config, nothing changes.

Still worth one end-to-end run on hardware with the ANE package: overlay built into boot.bin by update-m1n1, boot check passing, clean reboot.

@maralcbr this got more urgent overnight: omarchy-mac-boot 20261004-2 and omarchy-ane-dkms 0.4.5 are both on edge now, so the first real overlays have shipped. On a Mac whose owner edited /etc/default/update-m1n1 before the upgrade, pacman keeps their copy without the overlay call, and installing the ANE package makes the boot check fail a correct boot.bin and stop omarchy update. I've updated the Merge Danger section above to match. Worth merging and re-pinning omarchy-mac-boot soon if it looks right to you.
