Function usePipelinePollDeltas

usePipelinePollDeltas(pollID: string): PollOptionDelta[]
Fetch the latest server-computed deltas for a single poll id, or [] if the poll has only ever been seen via tick (no realtime updatePoll push yet).

Memo-stable: returns the same [] reference across renders when the poll has no recorded deltas. Pair with usePipelinePolls(id) to drive "+$X just landed on option Y" animations.
Parameters
- pollID: string
Returns PollOptionDelta[]
Example
```
const deltas = usePipelinePollDeltas(poll.id);
deltas.forEach(({ optionID, amountRaisedDelta }) => animate(optionID, amountRaisedDelta));
```
