Struct WeightGuard 

struct WeightGuard<Key, Val, We: Weighter<Key, Val>, B, L, Plh: SharedPlaceholder> {
    shard: *mut CacheShard<Key, Val, We, B, L, Plh>,
    idx: NonZeroU32,
    old_weight: u64,
}

Drop guard for entry_or_placeholder: if the user callback panics after mutating the value, recomputes weight to keep shard accounting consistent.
