feat(standalone): env-selected Yjs provider abstraction (ysync 0004)

Browse source 
Generalize the collab transport into a provider registry (none |
broadcastchannel | partykit | hocuspocus), one active per env. startCollab
takes { provider, room } and awaits provider.whenSynced() before seed/adopt.
Network libs lazily imported; room id from @pcbjam/shared collabRoomId.
