Possible CAN frame flags. The flag value must match the canlib flag value.
NOTE (known proto3 deviation): The zero value is STATUS_LEVEL_NONE rather than
STATUS_LEVEL_UNSPECIFIED because the backend maps these values directly to an
internal status level enum where 0 = None (no status set). Changing the zero
value would require cascading changes across the service implementation.
