docs(runway): state the merge target atomicity guarantee in the contract - #722

A committing merge has always been all-or-nothing against its merge target by construction of the Git merger, but the property was only written down in the Git merger's own README. This documents it as part of the Merger interface contract, the published wire contract README, and the Runway workflow RFC, so callers and future backends can rely on it without reading the Git implementation.

Writes down, as part of the written contract, a property that has always been true of Runway's committing merge by construction of the Git merger: it updates the merge target at most once per request, and afterwards either every step is reachable from the target or the target is unchanged. Adds this to the
