Add //nolint:errcheck comments to intentionally unchecked error returns:
- defer X.Close() calls: errors from closing read-only resources, rows
after iteration, files, response bodies, and gzip readers are not
actionable and don't affect correctness
- defer tx.Rollback(): standard Go pattern where rollback after
successful commit returns an error, which is expected behavior
- defer stmt.Close(): statements are closed with their transactions
- Cleanup operations: DeleteRevision on failure and os.RemoveAll for
temp directories are best-effort cleanup
- HTTP response encoding: if JSON encoding fails at response time,
there's nothing useful we can do
- Test/benchmark code: unchecked errors in test setup/cleanup where
failures will surface through test assertions
