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 * wip ack * wip fix ack * more logging * pending tracker * keep pending connections on errors * less logging * refactor model * refactor frombinarydata * idendityannouncement refactor and update to new binary protocol * fix keys * refix keys * dms work * revert to mainnet * do not change bluetooth adapter name * keep code but uncomment * clean up comments * cleanup comments
