HS: deferred-reraise in catch + exception event tests (+5)
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 20s
Details

Browse Source 
- compiler: wrap catch body in nested guard so (raise e) inside a
  catch handler defers the re-raise until after the guard exits,
  avoiding the handler-stays-active infinite loop
- generator: MANUAL_TEST_BODIES for rethrown/uncaught exception events,
  can-pick-detail/event-property, bootstrap bootstraps; remove from
  skip-list; regenerate behavioral spec
