Background
The current UI has run timeline primitives, tool cells, and a Run inspector, but a Codex-like agent console needs a more complete action history for understanding what happened across a run. Implementing this properly likely requires API/data-shape decisions, so it is out of scope for pure style polish.
Proposal
Add a richer run/action history view that groups:
- run lifecycle states and timing
- tool calls, approvals, cancellations, and errors
- generated/modified files tied to the run
- delegation child runs and aggregation results
Acceptance Criteria
- A user can answer "what did this run do?" from the inspector without scanning the whole chat.
- Tool/action entries are grouped and expandable.
- The view handles idle, running, failed, cancelled, and completed states.
