[NIT] In doRequest, after the handleResponse call, there's a check if resp.StatusCode == http.StatusTooManyRequests but resp could theoretically have been closed by handleResponse. The body is closed, but the resp.StatusCode field is still accessible on the struct. This is correct and safe in Go's net/http — just worth being aware of.

[MINOR] The mapCheckRunStatus mapping treats cancelled, skipped, and neutral as "success" (non-blocking). This is a policy decision that should be documented more prominently — cancelled in particular could reasonably be mapped to failure in some contexts. The comment // non-blocking is brief; a note explaining the design rationale (e.g. 'these do not indicate a blocking failure per GitHub's check suite semantics') would help future maintainers.
