User story

As an operator, I want to see per-turn cost / tokens / duration and any extended-thinking blocks the model emitted, so I know what each turn cost me and what the model considered.

Acceptance criteria

Per-turn meter

Each completed assistant bubble carries a footer pill showing <duration> · <input>+<output> tok · $<cost>. Data already lives in result.detail (see apps/server/src/infrastructure/event-log.ts:152).
Hover / focus reveals a tooltip with cache-creation + cache-read breakdown.
Session header shows running totals (sum across persisted turns).

Reasoning blocks

When the SDK emits a thinking block (Opus extended thinking), the transcript renders a collapsible "Reasoning" section above the assistant text. Default collapsed.
extractAssistantText is updated to skip thinking blocks for the streaming bubble's main text (renders separately).

Out of scope

Cost budgeting / cap UI (separate concern).

References

Data path: apps/server/src/infrastructure/agent/sdk-adapter.ts:107 (extractAssistantText) and event-log.ts:152 (result.detail).
Spec: specs/workspace-chat-overhaul.md § P3.
