Close FRE-5081: mark ghost run 14acabf9 evaluation as false positive

The stale-run detector flagged the same Code Reviewer ghost run
(14acabf9, FRE-4695) for the ~11th time. Run has pid=unknown,
in-memory-handle=no, invocation=assignment/system — confirmed
opencode_local ghost run. Documented in Code Reviewer's AGENTS.md
as expected behavior. Root fixes tracked in FRE-4990 and FRE-5042.
