Carry aquamarine 0.15.1 on edge for Apple Silicon and rebuild Hyprland

Carry Arch's aquamarine 0.15.1-1 with one patch that re-reads a connector's
possible CRTCs on rescan, so a Type-C port the Apple DCP fabric reroutes to
another pipeline gets a CRTC without restarting the compositor. aarch64 and
edge only; pkgrel 1.1 sits above Arch Linux ARM's 0.15.1-1.

Bump Hyprland for aquamarine 0.15.1 and make rebuild detection see aarch64.
sync-rebuilds followed PUBLISHED_ARCHES (x86_64 by default), so the scheduled
run skipped every aarch64-only package, and it read aarch64 triggers from Arch
Linux ARM even when this repository carries them. It now follows the
architectures a merge builds, and reads a carried trigger from its recipe once
edge publishes that version.
