release: v0.0.9 lockstep — re-anchor to clean embedded artifacts

The zddc-server-v0.0.9 (and sibling) tags previously pointed at a
commit whose embedded versions.txt + tool HTMLs still carried
alpha-dirty labels — the cut process regenerated these in the
working tree but never folded them into the tagged commit. The
binary built from that tag (used by tnd-zddc-chart's prod
Dockerfile) embedded the alpha labels.

This commit folds the stable-labeled artifacts in. The seven
v0.0.9 tags are force-moved to point here so future binary builds
from `ZDDC_REF=stable` get clean stable bytes baked in. The
old commit (a02a26d) remains in history; just no tag references
it anymore.

Sustainable fix to ./build's release flow (commit before tag,
skip embedded mutation on plain dev/alpha cuts) is a separate
follow-up — this commit only fixes the in-flight state.
