- New ref guide page solrcloud-update-consistency.adoc stating the consistency model of /update in SolrCloud: acknowledgment semantics, durability, ordering, atomicity, visibility, optimistic concurrency, retry-ability, and leader failover - New dev-docs/distributed-update-internals.adoc: implementation deep-dive of the distributed update path (routing, fan-out, acknowledgment and error handling, shard terms) and versioning/optimistic concurrency, with an eye toward reasoning about idempotency and retries - AGENTS.md: add a Developer Docs Index so coding agents discover dev-docs/ when working on related topics Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

This new section looks very useful for agents, like a "map" of where to read more on dev topics. I like it.

I want more documentation about Solr's consistency model and on how Solr implements it. So I had Claude Fable work on producing this. Ultimately I want to discuss atomicity / idempotency... that's either a follow-on conversation or could very well happen here.
The first commit here is submitted with zero a-priori review; I will review it momentarily here and hopefully others will to.
