fix(comment-checker): handle apply_patch payloads

Accept apply_patch edits from nested result/metadata file lists and from raw patchText args when OpenCode does not provide direct metadata.files.

Forward tool args through the after-hook pipeline so comment-checker can inspect raw apply_patch inputs while preserving existing write, edit, and multiedit routing.
