Findings addressed: - F1/G1: Add doc comment to GetAllFilesInPath documenting fail-fast contract - F2/G2: Add explicit backslash-prefix guard to skip '\ No newline' markers - F3: Add comment explaining position > 0 guard (skip lines before first hunk) - F4: Refactor parseHunkNewStart to use strconv.Atoi instead of per-char concat - F5: Add error propagation tests (ListContents, GetFileContent, nested, ctx cancel) - F6: Wrap errors.ErrUnsupported in DismissReview for programmatic checking - S1: Add ctx.Err() checks + max file count/byte constants with clear errors - S2: Addressed by S1 — input bounds are now enforced via the same constants
