* wip

* fix(wifi-aware): use bindSocket and scoped IPv6 instead of bindProcessToNetwork

* Merge branch 'upstream/main' into fix/wifi-aware-socket-binding

* Fix Wi-Fi Aware connectivity and UI integration post-merge

- Replace bindProcessToNetwork with bindSocket for VPN compatibility.
- Implement Scoped IPv6 address resolution (aware0) for mesh routing.
- Bridge Wi-Fi Aware incoming messages to AppStateStore for UI visibility.
- Fix syntax errors and variable name conflicts in Debug UI.

* Enhance Wi-Fi Aware robustness and debug UI display

- Clean up transport resources (sockets, server sockets, network callbacks) immediately on peer disconnection.
- Implement resolveScopedAddress to show scoped IPv6 (e.g., %aware0) in Debug UI.
- Fix Map type mismatch warning in ChatViewModel bridge.
- Filter self-ID from peer cleanup tables to prevent recursive self-removal.

* Share GossipSyncManager across transports to prevent redundant message synchronization

- Registered BluetoothMeshService's GossipSyncManager as a singleton in MeshServiceHolder.
- Modified WifiAwareMeshService to use the shared GossipSyncManager if available.
- Added background cleanup for peer mappings on socket disconnection.
- Fixed Kotlin type mismatch during nickname map merging.

* Restore VPN acquisition logic and improve peer cleanup

- Revert removal of NET_CAPABILITY_NOT_VPN to allow hardware handle acquisition while VPN is active.
- Refactor handlePeerDisconnection to more reliably cleanup initial and routed IDs.
- Switch cleanup logging to debug level to reduce log noise.
