I have removed the `CONFIGURE_MEMORY_OVERHEAD` entirely. As Michal confirmed, the \~404 bytes fit within the default `RTEMS_MINIMUM_STACK_SIZE`, which is automatically provisioned via the new `_CONFIGURE_CAN_TASKS` macro. I have verified that the test passes cleanly on the `sis` simulator without any artificial memory overhead or extra stack padding.
