omarchy-ane-dkms: ANE on by default on T6021

omarchy-ane removed omarchy-ane-m2-enable and the modprobe gate
packaging/modprobe/ane_t6021.conf, and added 90-omarchy-ane-firmware.hook,
which fetches the T6021 firmware after each install and upgrade
(omarchy-ane receipts/2026-10-01-t6021-default-on).

- package(): install the firmware hook; drop omarchy-ane-m2-enable, the gate
  file and its backup=() entry. On upgrade pacman deletes an unchanged gate
  file; a changed one becomes ane_t6021.conf.pacsave, which modprobe does not
  read (it reads only *.conf).
- post_remove: remove both firmware files that omarchy-ane-firmware-fetch
  writes (T602x and T8112). Drop the ane-t6021 opt-in edit: no overlay reads
  that key now.
- The overlay comment names /usr/share/omarchy-platform/dtb-overlays.
