Feature description

The remote layer was recently refactored to expose commits and pull requests as streams (PR #1272). While this clears the way for smarter request strategies and performance improvements, the downstream code
still eagerly collects these streams into Vecs and processes them in a non-streaming fashion.

As a result, the current implementation does not yet benefit from:

• early exits
• reduced API requests

In other words, the streaming abstraction is not yet reflected end-to-end.

Desired solution

Adopt streaming semantics throughout downstream consumers so that commit and pull request data can be processed incrementally instead of being fully materialized upfront.

This issue is intended as a tracking issue, and the work can be implemented incrementally across multiple follow-up PRs.

Alternatives considered

• Keeping the current eager collection approach and relying on pagination limits or higher rate limits
• mplementing ad-hoc early-exit logic on top of fully collected result sets

These alternatives do not fully realize the benefits enabled by the stream-based remote refactor.
