Subject: [PATCH] ci(release-image): Skip setup steps when using persistent
 BuildKit

When BUILDKIT_ENDPOINT is set, builds run on a persistent BuildKit instance,
making runner setup steps unnecessary. Skip Rust toolchain installation,
QEMU setup, caching steps, and timelord to eliminate ~7 operations per job.

Also adds output to git SHA and timestamp steps for visibility.

Cuts at least a minute off average build time through fewer installs,
cache restores, and cache saves.
