memory: track low-pri cleanup of inert mood.decay_rate/stale_hours from deployed WT bind-mounts

R30 b15-b17 removed mood.decay_rate/mood.stale_hours from canonical (OCEAN
wall-clock OU replaced per-turn decay); deployed /opt/worldtree*/config
bind-mounts still carry them, harmless (CharacterSchema.mood is dict[str,Any]).
Tracked as an opportunistic edit-only/no-restart cleanup to restore byte-identity;
noted new optional mood.tau_base (unset->derived). Config-delta acked to worldtree-dev.
