This changeset adds new architecture internals documents to the contributing
guide. These are intentionally here and not on the public-facing website because
the material is not required for operators and includes a lot of diagrams that
we can cheaply maintain with mermaid syntax but would involve art assets to have
up on the main site that would become quickly out of date as code changes happen
and be extremely expensive to maintain. However, these should be suitable to use
as points of conversation with expert end users.
Included:
* A description of Evaluation triggers and expected counts, with examples.
* A description of Evaluation states and implicit states. This is taken from an
internal document in our team wiki.
* A description of how writing the State Store works. This is taken from a
diagram I put together a few months ago for internal education purposes.
* A description of Evaluation lifecycle, from registration to running
Allocations. This is mostly lifted from @lgfa29's amazing mega-diagram, but
broken into digestible chunks and without multi-region deployments, which I'd
like to cover in a future doc.
Also includes adding Deployments to our public-facing glossary.
