Fix the flaky retry test

Worked for 3m 12s

The flake is fixed and committed on fix/retry-flake.

Cause: the test asserted on wall-clock time and the jitter was unseeded, so on a slow runner the third attempt landed past the deadline.
Fix: backoff takes an injected clock and a seeded jitter source, and the test drives time itself.
Verification: 50 of 50 stress runs passed.

Nice. Do the same for the websocket reconnect test.

What you can do

Choose an agent for each chat

Start a chat with a machine, project folder, agent, model, and access level.
Work across several sessions

Run agents at the same time and follow their activity from one sidebar.
Handle approvals

Allow or deny requests without switching to the agent's terminal.
Review file changes

Open diffs, undo supported turns, and review worktrees before merging them.

Sessions run on the selected machine

Closing Mudskipper, putting your laptop to sleep, or losing the network connection does not stop a running agent. Open the app again to reconnect.
