Add recheck of message count after acquiring lock and before storing
continuation to prevent race where message arrives between initial
count check and continuation install.

Replace timing-based sleep() synchronization with continuation-based waiting
in FragmentationTests to fix intermittent failures.
Changes:
- Add thread-safe CaptureDelegate with NSLock for array access
- Add waitForPublicMessages/waitForReceivedMessages using CheckedContinuation
- Update reassemblyFromFragmentsDeliversPublicMessage to use proper waiting
- Update duplicateFragmentDoesNotBreakReassembly to use proper waiting
- Remove fire-and-forget Task blocks that caused race conditions
Root cause: Tests used fire-and-forget Tasks with sleep(0.5) but delegate
callbacks go through notifyUI() which spawns another MainActor Task.
The sleep didn't guarantee callback completion.

Synchronized access to readQueue and isSendingReadAcks using the
existing concurrent DispatchQueue with barrier flags:
- sendReadReceipt(): wrap enqueue in barrier async
- processReadQueueIfNeeded(): extract item within barrier context
- scheduleNextReadAck(): wrap callback in barrier async
This fixes race conditions where concurrent calls could corrupt the
read queue or cause check-then-act bugs on isSendingReadAcks.
Also adds thread safety tests:
- concurrentReadReceiptEnqueue: 100 concurrent enqueue operations
- readQueueProcessingUnderLoad: concurrent enqueue during processing
- isPeerReachableThreadSafety: concurrent read access test

Added secureClear() calls for all 6 DH operations in NoiseProtocol.swift
to properly clear sensitive shared secrets from memory after use:
- writeMessage(): .es initiator/responder, .se initiator/responder
- performDHOperation(): .ee and .ss operations
This fixes a forward secrecy vulnerability where shared secrets could
persist in memory after handshake completion.
Also adds:
- TrackingMockKeychain to count secureClear calls in tests
- 3 new tests verifying secureClear is called during handshake

Added @MainActor annotation to both LRUDeduplicationCache and
MessageDeduplicationService classes. This provides compile-time
enforcement of thread safety since all callers (ChatViewModel,
NostrRelayManager) are already on MainActor.
Benefits:
- Compile-time enforcement prevents future misuse
- Simpler than internal locking mechanisms
- Consistent with existing patterns in codebase
Also adds:
- @MainActor annotation to existing test suites
- 5 new concurrency tests verifying thread safety behavior

Fixes crash on macOS when presenting sheets due to missing @EnvironmentObject.
Added .environmentObject(viewModel) to 8 sheet/fullScreenCover presentations.
Fixed presentations:
- AppInfoView sheet
- FingerprintView sheet
- ImagePickerView fullScreenCover (iOS, both contexts)
- MacImagePickerView sheet (macOS, both contexts)
- ImagePreviewView sheet
- LocationChannelsSheet sheet
Tested on macOS 26.1 (Apple Silicon M4).
All sheet presentations now open without crash.
Platform: macOS only
Impact: Resolves EnvironmentObject.error() crashes
Pass the UserDefaults-backed sentReadReceipts from ChatViewModel to
consolidateMessages() to correctly identify already-read messages
after app restart. This prevents duplicate read receipts and incorrect
unread badges when reopening a chat shortly after reading it.
Addresses PR review feedback.
- Remove duplicate Regexes enum, use MessageFormattingEngine.Patterns
- Delete unused formatMessage() function (views use formatMessageAsText)
- Move message consolidation logic to PrivateChatManager
- Add consolidateMessages() and syncReadReceiptsForSentMessages()
- Wire PrivateChatManager to UnifiedPeerService for peer lookup
Reduces ChatViewModel from 5998 to 5713 lines (-285 lines)
All 303 tests pass
