Undo a deleted chat

New

• Deleting an agent removes it immediately and offers Undo for eight seconds. Quitting the app finishes the delete. Discarding a file's changes can be undone the same way when the previous contents can be restored.
• You can edit a message you already sent and resend it, or edit a queued follow-up and save it.
• While a run is live, the composer says whether the draft joins the current run or waits for the next turn.
• The command palette, the file picker, and the agent list match a partial name, and the matching letters are highlighted. An empty agent filter says so and can show every agent.
• Holding the shortcut modifier shows the rest of the shortcut on the control. An API key field can be revealed.

Fixed

• A timeout, a dropped network, an SSH problem, a missing permission, or GitHub not being signed in is named in plain language. The original detail stays available.
• A progress note that only announces the next tool stays out of the transcript. The answer leads with the outcome, including what was not verified.
