riccardom 0aeed6ae5b Removes confirm. Uses next offer to deliver confirmation/ack of previous round
We clock the next Offer initiation to the OnDataPathRekeyed, so we have 2 minutes
ahead of us to do our attempts and stuff before to give up.
On failure, we will know because we will not receive a new answer.. but more importantly
the wg handshake will fail :D

riccardom cec4bd49b4 Leave signal offer/answer as a pull/push operation not as an actual transport 2026-09-11 14:48:54 +02:00
riccardom 2ed0d3bf03 Assume two transports: initial "signal" (control plane) one (no data path established yet) + data path one
Define OnDataPathRekeyed event to transition from control plane path to data plane path over the WG tunnel.

Keep confirm ALWAYS on NEW established WG tunnel (posthandshake with rekeying). We keep an active method
irrelevant of the WG handshake (we might decide that the indirect wg handshake is sufficient in the future).

Optimistic commit on responder(when sending answer), while on initiator we set it on getting the answer

riccardom 661926ce3a Collapse Driver and Manager in one.
- Have just one manager => one lock
 - Session state is needed in driver to => we have it available now.
 - Isomorphically align to rosenpass components and functionality
