Now that both the agent image (a68d1c4d, via the kustomize images: override)
and the hux sidecar (build-39) are multi-arch with amd64 leaves, move the worker
onto the amd64 accelerator titan-22:
- Add an OR'd nodeSelectorTerm for amd64 + node-role.kubernetes.io/accelerator +
hostname titan-22, with NO worker=true requirement. Keep the arm64 pi-fleet
term as an OR'd fallback so the worker is never stranded.
- Strong primary preference: hostname=titan-22 at weight 100 (scheduler max),
pi-fleet rpi5 nudge lowered to 50, so hermes actually lives on titan-22.
- Tolerate node-role.kubernetes.io/accelerator=true:NoSchedule (harmless where
absent) and the soft atlas.bstein.dev/media-primary:PreferNoSchedule that
titan-22 currently carries, so the weight-100 preference is not offset and
placement is deterministic.
Completes the titan-22 effort the flip branches missed; the earlier branches
never repointed to multi-arch images, which is why the worker never landed here.
