Show the agent’s to-do list (TodoWrite) live during normal runs

Problem or use case

During normal (non-plan-mode) runs, agents keep a to-do list (Claude Code's TodoWrite, OpenCode's todowrite), but I can't find it anywhere persistent in the UI. The thread menu shows branch, Git and changes info, but no to-dos. To see progress on a long run, I have to scroll the transcript for the latest update, which is especially hard on remote clients like app.t3.codes.

Related: #1387, which mapped TodoWrite to plan events for the plan sidebar.

Proposed solution

A persistent panel or sidebar section showing the active thread's latest to-do list:

• Each item with its status: pending, in progress, completed
• Updates live as the agent changes statuses
• Works in normal runs, not only plan mode
• Hidden when the thread has no to-dos

Smallest useful scope

A read-only list of the current thread's latest to-dos with status indicators, updating live.

Alternatives considered

• Scrolling the transcript: slow on long threads and hard on mobile.
• Plan mode's plan view: only covers plan-mode runs.
