v26.6.3, build 243 (2026-06-xx xx:xx UTC)

Improved all assistants, so running tasks can continue when you leave the assistant and return later.
Improved the assistant overview so it shows which assistants are still running or have a result ready.
Improved the activity indicators for running chats and assistants so they use a consistent blue highlight.
Improved the chat experience by automatically focusing the message composer again when it becomes available. Thanks, Dominic Neuburg (donework), for the contribution.
Upgraded Rust to v1.96.1
