This commit improves VoiceOver support by adding descriptive accessibility labels to all icon-only buttons and visual indicators in the app. This ensures users with visual impairments can understand and interact with all UI elements.
Changes made:
- Send message button: Added label "Send message" with context-aware hints
- Navigation buttons: Added "Back to main chat" labels for back arrows
- Favorite stars: Dynamic labels that change between "Add to favorites" and "Remove from favorites"
- Lock icons: Context-aware labels for password protection status
- Signal strength indicators: Descriptive labels (excellent/good/fair/poor) instead of color-only information
- Unread message indicators: Clear labels for envelope and number icons
- People/channel counts: Proper pluralization and descriptive text
- Save/bookmark buttons: Labels indicating retention enable/disable action
Technical details:
- Used .accessibilityLabel() for descriptive text
- Added .accessibilityHint() for additional context where helpful
- Used .accessibilityHidden(true) to hide redundant decorative elements
- All labels are dynamic and update based on current state
This change ensures BitChat meets WCAG accessibility guidelines and provides a better experience for all users.

- Improve completion handling in share extension
- Check for shared content when app becomes active
- Fix async handling of shared content processing
- Introduce thread safety for recentlySentMessages using NSLock to prevent race conditions.
- Adjust message delay parameters for faster synchronization: reduce min/max message delays and adjust initial announce timing.
- Update sendMessage and sendEncryptedRoomMessage methods to accept optional messageID and timestamp parameters for better tracking.
- Improve message deduplication logic in ChatViewModel to prevent duplicates from being added when echoing back sent messages.
- Modify MessageRetryService to include original message ID and timestamp for better retry handling.

- Detect when users take screenshots on iOS
- Send system notification to all participants
- Works in public chat, channels, and private messages
- Display screenshot notifications as system messages
- Change @user to @name in all documentation
- Change 'blocked users' to 'blocked peers' for consistency
- Add /block and /unblock commands to autocomplete menu
Implemented user blocking functionality:
- /block <nickname> - blocks a user from private messaging and ignores their messages in channels
- /block - lists all blocked users
- /unblock <nickname> - unblocks a user
Implementation details:
- Blocks are stored by public key fingerprint for persistence across sessions
- Blocked users cannot send private messages or have their public messages displayed
- Blocked users are silently ignored (they don't know they're blocked)
- Blocking a user automatically removes them from favorites
- Added getPeerPublicKey() method to BluetoothMeshService for accessing peer identity keys
Fixed multiple threading issues that were causing crashes when users sent messages:
- Added NSLock to synchronize access to recentlySentMessages Set
- Fixed thread-unsafe access to activePeers Set using existing lock
- Removed force unwrapping that could cause crashes
- Added defensive input validation for message sending methods
These fixes address crashes reported in TestFlight where the app would crash when typing and sending messages.

- Added welcome message for new users (3 second delay)
- Changed sidebar header to 'YOUR NETWORK'
- Added command aliases (/join, /msg)
- Implemented /hug and /slap commands with haptic feedback
- Improved command help display with alphabetization
- Renamed 'rooms' to 'channels' throughout entire codebase
- Fix race condition where recentlySentMessages Set was being modified from different queues
- Move all Set.remove operations to messageQueue instead of main queue
- Prevents EXC_BREAKPOINT crash when removing elements during concurrent access
Critical fixes:
1. Match messages by sender nickname in addition to peer ID (since peer IDs change)
2. Send read receipts to CURRENT peer ID, not old senderPeerID from message
3. Remove requirement for senderPeerID to be non-nil (blocks older messages)
4. Add extensive logging to trace the flow
The core issue was that peer IDs are ephemeral and change between sessions:
- Rick sends message with peer ID A
- Later, Jack connects to Rick who now has peer ID B
- Read receipt needs to be sent to B, not A
- Messages need to be matched by nickname, not just peer ID
