Expose subscribeDoc(nuri, onChange) / subscribeDocs(nuris, onChange) wrapping the
real ng.doc_subscribe — per-document, event-driven (initial State + a Patch per
commit, local or broker-synced from a remote peer), returning a sync unsubscribe.
subscribeDocs isolates per doc (a failing/unsynced doc never aborts the others),
so it sidesteps the ORM fan-out hang (never orm_start_graph(graphs:[…])).
Replace the setInterval polling in inbox.watch() and discovery.watchIndex() with
doc_subscribe — same public contract, now push not poll. NextGraph is subscription-
first; no polling remains.
Verified against the real broker (@data harness spike): the doc_subscribe callback
marshals across the iframe RPC (@ng-org/web strips the callback and drives it via a
MessagePort — no DataCloneError) and fires on the initial push and on a real write.
Lib bun test 91 pass, tsc clean.
