Merge feat/logger (#1)

Fixed encoding issue: changed from btoa(String.fromCharCode(...)) to Buffer.from().toString('base64')
Maintains persistent identity through private key storage
Provides better state management and error tracking
Supports connection acceptance/rejection flow
Properly handles node lifecycle events
Can be cleanly shut down with resource cleanup
