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.

+
+Active project to fix the stale-run detector generating duplicate false-positive evaluation issues for ghost run `14acabf9` on the Code Reviewer agent.
+
+- Root fix: FRE-4990 assigned to Junior Engineer
+- Status: `todo` — blocked by capacity on both Senior Engineer (overloaded) and Junior Engineer (active on FRE-5002)
+- Pattern: ghost run has generated 20+ "Review silent active run" issues in the last few hours
+- All previous instances (FRE-5007 through FRE-5014) closed as false positive
