3101b74580 (index) Move to a lexicon-free index design
This is a system-wide change.  The index used to have a lexicon, mapping words to wordIds using a large in-memory hash table.   This made index-construction easier, but it
also added a fairly significant RAM penalty to both the index service and the loader.

The new design moves to 64 bit word identifiers calculated using the murmur hash of the keyword, and an index construction based on merging smaller indices.

It also became necessary half-way through to upgrade guice as its error reporting wasn't *quite* compatible with JDK20.

460998d512 (index) Move index construction to separate process.
This provides a much cleaner separation of concerns, and makes it possible to get rid of a lot of the gunkier parts of the index service.  It will also permit lowering the Xmx on the index service a fair bit, so we can get CompressedOOps again :D

1e6800565a (system) Remove EdgeId<T> and similar objects
They seemed like a good idea at the time, but in practice they're wasting resources and not really providing the clarity I had hoped.

6a04cdfddf (loader) Implement new linkdb in loader
Deprecate the LoadUrl instruction entirely. We no longer need to be told upfront about which URLs to expect, as IDs are generated from the domain id and document ordinal.

For now, we no longer store new URLs in different domains.  We need to re-implement this somehow, probably in a different job or a as a different output.
