refactor: decouple Histogram slot capacity from VecDeque allocation size

`VecDeque::with_capacity(n)` may allocate more than `n` slots, causing
`Histogram::advance()` to retain more slots than intended since it used
`VecDeque::capacity()` to decide when to evict. This led to unbounded
slot growth when the allocation overshot.

Extract `SlotQueue<T>` to track the logical capacity separately from
the `VecDeque` allocation, so eviction always respects the requested
slot count.
