bumpValidatedAt

open suspend override fun bumpValidatedAt(z: Int, x: Int, y: Int)

Refresh a tile's freshness timestamp WITHOUT rewriting its bytes — the conditional-GET 304 Not Modified path. Restarts the stale-while-revalidate window so a still-current tile isn't re-requested every frame. Default no-op for stores that don't track freshness.
