FN-6591: stabilize dist task-list barrel tests

Browse Source 
Stabilize the @fusion/core task-list dist barrel guard without weakening its coverage.

- Load the built dist core barrel once in beforeAll when dist artifacts exist.
- Reuse the cached runtime module across dist export and fn_task_list surface assertions.
- Keep the source barrel and real runtime export path coverage intact while reducing duplicate dynamic import pressure.

FNXC:CoreTests 2026-06-17-13:40:
FN-6591 requires the FN-6515/FN-6535 dist-barrel guard to settle under broad @fusion/core suite load without timeout, retry, or worker appeasement.
Load the built dist barrel once for every dist assertion so heartbeat fn_task_list coverage still exercises the real runtime export path while avoiding duplicate dynamic-import pressure in the timed test bodies.
