ChatTransportEventCoordinator, ChatPeerIdentityCoordinator,
ChatMediaTransferCoordinator, ChatVerificationCoordinator, and
ChatLifecycleCoordinator drop their unowned ChatViewModel back-refs for
narrow @MainActor contexts (20-36 members each), reusing shared
witnesses across protocols. The two remaining raw writers of
sentReadReceipts now route through owner intent ops
(unmarkReadReceiptsSent, syncReadReceiptsForSentMessages), closing the
gaps noted in the previous commit. NoiseEncryptionService stays fully
out of the verification coordinator via installNoiseSessionCallbacks.
26 new mock-context tests.

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.
