Decoupling the channel-message event bridge onto an @Async listener means the
downstream workflow run is produced off the event-publishing thread. The test
read the run table synchronously right after publishEvent, racing the listener
— the positive cases failed and the negative cases passed for the wrong reason.
Poll briefly for the run (positive) / give the listener time then assert none
(negative) so the test reflects the async dispatch semantics.
The PRIVATE_ITEMS list contained the bare 'test' entry, which rsync
interprets as 'any directory named test at any depth' — so it caught
the root-level /test/ scratch directory (intended) AND every src/test/
under each module (not intended).
Pattern is already anchored to /test (root-only). This commit rsyncs
the accumulated src/test/ tree forward so opensource has the unit tests
that have been written / updated against existing src/main/ code since
the pattern regression. Going forward each per-commit sync will carry
src/test/ files along with the main change.
