chore: remove verify-notify-domain step from persona-community tree

Under the shared-host model, all *.threesix.ai projects use the pre-provisioned
platform host (threesix.ai) which is already Resend-verified. There is no
per-project DNS/Resend domain to wait for — the step was a no-op and just
burned 30 seconds minimum. Removed and wired implement-persona-model directly
to wait-infra.
