Core Features
Unread Message Tracking: Added persistent unread counts for contacts and channels with visual badges
Message Deletion: Users can now long-press to delete individual messages in chats and channels
SMAZ Compression: Added per-contact compression settings (previously only channels)
UTF-8 Length Limiting: Text inputs now enforce protocol byte limits correctly
Channel Message Paths: New screen to visualize packet routing through repeater network with map view
Protocol Updates
Added maxContactMessageBytes() and maxChannelMessageBytes() helpers for message length validation
Changed channel PSK format from Base64 to Hexadecimal (breaking change)
Added app version field to connection handshake frame
UI Improvements
Unread badges on all contact and channel list items
Enhanced message bubbles with path visualization for channel messages
Character count displays in message input fields
Improved repeater CLI screen functionality
