-Store public key and peer ID in peerstore during handshake
-
-Modified the InsecureTransport class to accept an optional peerstore parameter and updated the handshake process to store the received public key and peer ID in the peerstore when available.
-
-Added test cases to verify:
-1. The peerstore remains unchanged when handshake fails due to peer ID mismatch
-2. The handshake correctly adds a public key to a peer ID that already exists in the peerstore but doesn't have a public key yet

-Fixed several flow-control and concurrency issues in the ``YamuxStream`` class. Previously, stress-testing revealed that transferring data over ``DEFAULT_WINDOW_SIZE`` would break the stream due to inconsistent window update handling and lock management. The fixes include:
-
-- Removed sending of window updates during writes to maintain correct flow-control.
-- Added proper timeout handling when releasing and acquiring locks to prevent concurrency errors.
-- Corrected the ``read`` function to properly handle window updates for both ``read_until_EOF`` and ``read_n_bytes``.
-- Added event logging at ``send_window_updates`` and ``waiting_for_window_updates`` for better observability.
