1dafa0c74d (mqapi/control) Repair repartition endpoint, deprecate notify endpoints.
The repartition endpoint was mis-addressing its mqapi notifications, omitting the proper nodeId.  In fixing this, it became apparent that having both @MqRequest and @MqNotification is a serious footgun, and the two should be unified into a single API where the caller isn't burdened with knowledge of the remote end's implementation specifics.

09917837d0 (process) Ensure construction exceptions are logged
Wrapping these exceptions in a try-catch and logging them with slf4j will ensure they end up in the process logs.

The way it worked using the default exception handler, they'd print on console (which nothing captures!), leading to a very annoying debugging experience.

f58a9f46be (loader) Don't truncate the entire links table on load
This behavior is an old vestige from the days of only having a single loader process.  We'd truncate the links table because doing inserts/updates was too slow.  This was also important because we had 32 bit ID, and there's a lot of links between domains to go around...

Instead we delete the rows associated with the current node with a stored procedure PURGE_LINKS_TABLE.

We also update the PRIMARY KEY to a BIGINT.  We'll need to load the data in excess of billion times to hit an ID rollover, so it'll be fine.

f613f4f2df (array) Fix spurious search results
This was caused by a bug in the binary search algorithm causing it to sometimes return positive values when encoding a search miss.

It was also necessary to get rid of the vestiges of the old LongArray and IntArray classes to make this fix doable.

* Add node-affinity to message queue

dbe9235f3a (*) Upgrade to JDK21 with preview enabled.
... also move some common configuration into the root build.gradle-file.

Support for JDK21 in lombok is a bit sketchy at the moment, but it seems to work.  This upgrade is kind of important as the new index construction really benefits from Arena based lifecycle control over off-heap memory.
