Why?

Provides a way to perform conflict analysis rooted in a build graph as opposed to file overlaps or all conflicts.

What?

Adds an RFC for a Tango-backed conflict.Analyzer that stores each batch's changed targets as a signature of 64-bit IDs in a durable store with an in-memory cache, and treats batches as conflicting when their signatures share an ID.

Test Plan

Docs only change - Implementation to follow.
