Subject: [PATCH] decay: don't bump version for weight-only changes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Decay is metadata, not content. Bumping version caused unnecessary
log churn and premature cache invalidation.

Also disable auto-decay in scheduler — was causing version spam
and premature demotion of useful nodes.
