Amarula.Protocol.AppState.SyncAction (amarula v0.1.0)

Turn a decoded app-state mutation (Amarula.Protocol.AppState.Patch output) into a consumer-facing change, ported from Baileys processSyncAction (chat-utils.ts).

A mutation's index is [type, id, msg_id, from_me] and the SyncActionValue carries the change. We map the chat/contact-relevant ones to %Amarula.Chat{} / %Amarula.Contact{} tagged tuples; everything else is {:other, action} so nothing is silently lost.

Pure: decode/1 takes a mutation map, returns a tagged result.
