cook: two default dishes (phyllomeos, phyllomeos-headless) + guest/experimental tiers; CI builds raw images

Manifest groups get a tier; only `default` is generated (make all TIER=...,
--tier). Default: phyllomeos (GNOME + virt-manager) and phyllomeos-headless,
Fedora 44, systemd-boot, CPU-agnostic hypervisor ingredient (hypervisor_type:
any). guest tier: guest-server, guest-desktop. experimental: biosboot/grub,
encrypted, rawhide. Generator clears stale recipes/dishes before writing.

build-image.sh: --dish and --tier; deploy.sh: --tier. build-iso.yaml replaced
by build-image.yaml: raw images for both editions on the fedora:host runner
(TMPDIR=/var/tmp, max-parallel 1), attached with the flattened kickstarts to
tagged releases. Live edition no longer built.
