Subject: [PATCH] fix: send appVersion in probe client hello and update it on
 session resume

buildClientConfig in test-daemon-connection.ts never set appVersion, so
probe clients (which become the live client) sent hello without it. The
daemon's version gate then hid Pi/Copilot from all these sessions.

Also update appVersion on the Session when a client reconnects with a
newer version, so stale sessions don't stay gated forever.
