- Companion radio stats: poll and display noise floor, RSSI, SNR, airtime with dedicated ValueNotifier and ref-counted polling - Adaptive RF-aware TX backoff based on radio conditions instead of fixed 5s - Variable-width path hash support (1-3 bytes per hop) - Air activity dot indicator in app bar with tap to open stats screen - Jump to oldest unread setting for chat screens - 1s send cooldown on DM and channel messages - Link style: theme-aware orange, added EmailLinkifier - New languages: Hungarian, Japanese, Korean - Remove dead DeviceScreen and BatteryIndicatorChip - Remove wakelock_plus dependency - TX power fields now read as signed int8
