GetDifferences and GetCommentsForPullRequest APIs were not handling pagination (NextToken), silently truncating results for large PRs. Blob fetches fired all at once (N files × 2) causing API throttling. - Add pagination loop for GetDifferences in both PR detail and commit diff - Add pagination loop for GetCommentsForPullRequest - Limit concurrent blob fetches to 5 via worker pool pattern - Extract shared fetchBlobTexts helper used by both PR and commit views https://claude.ai/code/session_01MyhBKncxxkLaLfCRxge4yC
getCommitsForPR previously walked only parentIds[0] sequentially. For PRs with merge commits, this followed the wrong branch and made up to 100 sequential API calls before hitting MAX_COMMITS. Rewrite to BFS: each level fetches commits in parallel, all parents are visited, and mergeBase is pre-marked as visited to stop correctly. Also add concurrency control (5 workers) to getReactionsForComments, which was firing all reaction fetches in parallel with no limit. https://claude.ai/code/session_01MyhBKncxxkLaLfCRxge4yC
