1. DVM response timeout. FavoriteDvmOrchestrator now times out after 20s if neither a 6300 response nor any 7000 status arrives, and sets errorMessage = "timeout" on the snapshot so the home banner switches from the "Asking…" spinner to a Retry button instead of hanging forever. 2. Tests. FavoriteDvmListEventTest covers create/add/remove round trips and the fixed-empty d-tag invariant; FavoriteDvmTopNavFilter match by id and by `a` address; FilterHomePostsByDvmIdsTest covers the two-relay-set split (content fetch on user relays, listen on DVM relays) and the multi-requestId merge case. Also registered kind 10090 in EventFactory so Quartz can deserialise FavoriteDvmListEvent (required for the round-trip tests and for reading the list back from relays). 3. Merged "All favourite DVMs" chip. New TopFilter.AllFavoriteDvms that unions every favourite's latest 6300 response into one feed. AllFavoriteDvmsFeedFlow uses flatMapLatest over the favourite-list flow so subscriptions rewire when the user adds/removes a DVM. FavoriteDvmTopNavPerRelayFilterSet now carries Set<HexKey> requestIds (was a single nullable) so the filter can subscribe to N kind 6300/7000 streams in one REQ per DVM relay. Banner renders "Asking your favourite DVMs for feeds…" while all are pending and a single Retry-all on collective error; pull-to-refresh re-issues every DVM's kind-5300.
