jif 78dc250384 Stop rollout reads when the calling task is cancelled (#53947) ...

## Why

Blocking rollout reads can continue decompressing and scanning history after the calling async task is dropped.

## What changed

Propagate caller cancellation through rollout readers, prefix validation, model-context scans, history materialization, and working-directory lookup. Check cancellation during compressed input and output, bounded reads, seeks, and between history records. Return an error on cancellation so partial history cannot be mistaken for a complete read.

## Testing

Add regression coverage for dropping a caller during decompression, cancelling compressed input and output (including skippable frames), cancelling reads and seeks on plain and decoded snapshots, and cancelling history materialization between records.
