v2.4.0

Removed

• Dropped stale-serving and the stale_version_depth config option. It did shave latency off reads during a rebuild, but readers already wait on a wake channel in that window — the added complexity wasn't worth maintaining for that marginal win, so the build-lock path is simpler now.

Fixed

• A malformed scalar/count/result cache entry (wrong shape for its kind) no longer recomputes from the database on every single read until TTL expiry — the first read after corruption now repairs the entry.
