Convert shared coordinator state to owner-side intent operations

Browse Source 
nostrKeyMapping, sentGeoDeliveryAcks/sentReadReceipts dedupe,
isBatchingPublic, geo subscription lifecycle, and private-chat selection
hand-off now mutate through single intent operations on ChatViewModel,
with backing storage locked down via private(set) so the single-writer
property is compiler-enforced. Context protocols downgrade to read-only
access where reads remain. 8 new contract tests.

Known remaining writers outside the protocols: sentReadReceipts is
passed inout to PrivateChatManager.syncReadReceiptsForSentMessages and
un-marked by ChatTransportEventCoordinator on disconnect.
