callebtcandGitHub c3c395832c Implement Noise XX Handshake Protocol for Direct Messages (#180)
* noise

* works?

* noise

* temporary

* better

* wip: use subnet

* better

* barely working

* werk

* subnet

* fix peer ID

* 8 byte peer ID

* wip noise

* wip fixes for noise

* std lib for noise

* noise handshake one step further

* buffers

* use fork

* fix imports

* simplify counter

* remove trash

* hashing

* no prologue

* nice

* wip, use noise encryption

* peer ID hex

* simplify session manager

* heavy logging

* use singleton

* Fix Noise session race condition with elegant per-peer actor serialization

- Use Kotlin coroutine actors for per-peer packet processing
- Each peer gets dedicated actor that processes packets sequentially
- Eliminates race conditions in session management without complex locking
- Single surgical change in PacketProcessor - minimal, maintainable
- Leverages Kotlin's native concurrency primitives

* decrypt correctly

* iniator works now

* clean code and fix signature to null

* better

* no signature in private message

* small fixes

* refactor ack

* refactor but untested

* messages working

* do not change bluetooth adapter name

* keep code but uncomment

* clean up comments

ShilohEye 33d273f268 Fix Android fragmentation for iOS/Rust compatibility
- Changed MAX_FRAGMENT_SIZE from 500 to 150 bytes to match iOS/Rust
- Fixed fragment ID generation to use 8 random bytes instead of string
- Implemented automatic fragmentation in BluetoothConnectionManager
- Added 20ms delay between fragments to match iOS/Rust implementation
- Updated fragment calculation to account for full packet overhead (34 bytes)

This ensures Android-generated fragments fit within iOS's default 185-byte BLE MTU,
fixing issues with commands like ?ls -la and ?ifconfig failing on iOS devices.
