Subject: [PATCH] test(session-title): mark the assertNever guard arm
 v8-ignored

The default arm of copySessionTitleSource is a closed-union exhaustiveness
guard (compile-time protection for the next kind); it is unreachable at
runtime, so the per-file coverage gate ignores it like every other
assertNever arm.
