shellcheck: fix read usage in result_parse and annotate intentional splitting

Use read -r for .res file and line parsing in Runner/utils/result_parse.sh
to address SC2162.

Also add a targeted SC2086 annotation for the intentional whitespace
splitting used to parse testcase name and result fields from each line,
without changing the existing result parsing behavior.
