Compile-time support for AgentSpaces annotations in Micronaut: maps the
core method annotations (@SpaceTake, @SpaceNotify, @BidFunction, @Ballot,
@OrderedTake, @OnDecision, and the 0.4.0 set @SpaceJoin, @Propose,
@OnEstimate, @SpaceReduce) to @Executable and @ReflectiveAccess, so a bean
with only method annotations enrolls at startup and native images keep the
reflection the binder needs. Goes on the annotation-processor path only.
