Atomic ops

The single write primitive. Verbs compose lists of AtomicOps and hand them to NogginStore.apply(ops) in one call; providers execute the list atomically — either every op lands or none do.

Most consumers never touch this API directly; they use verbs or their bound-method equivalents. Providers implement apply(ops) by delegating to applyOps after taking whatever locking their backing store needs. Custom-provider authors and tests that construct documents offline are the other two audiences.

• AtomicOp — the discriminated union.
• applyOps — apply a list of ops to a document in-place + validate. Throws NogginError on any structural problem in the resulting document.
• Document utilities — validateDocument, normalizeDocument, documentsEqual, diffDocuments, freezeDocument. The pure-function toolkit providers use to keep their in-memory doc, on-disk doc, and change-event pipeline in sync.
