- **ThinkingBlock** - Added `ThoughtStep` type and UI handling for step kinds: `thought`, `tool_call`, `tool_output`, and `done`. - Integrated `Check` icon for completed steps and formatted duration (seconds) display. - Implemented streaming paragraph extraction, fade‑in/out animation, and improved loading state handling. - Updated header to show dynamic titles (thinking/thought + duration) and disabled expand/collapse while loading. - Utilized `cn` utility for conditional class names and added relevant imports. - **ThreadContent** - Defined `ToolCall` and `ThoughtStep` types for type safety. - Constructed `allSteps` via `useMemo`, extracting thought paragraphs, tool calls/outputs, and a final `done` step with total thinking time. - Passed `steps`, `loading`, and `duration` props to `ThinkingBlock`. - Introduced `hasReasoning` flag to conditionally render the reasoning block and avoid duplicate tool call rendering. - Adjusted rendering logic to hide empty reasoning and ensure tool call blocks only appear when no reasoning is present. - **useChat** - Refactored `getCurrentThread` for clearer async flow while preserving temporary‑chat behavior. - Captured `startTime` at message creation and computed `totalThinkingTime` on completion. - Included `totalThinkingTime` in message metadata when appropriate. - Minor cleanup: improved error handling for image ingestion and formatting adjustments. Overall, these changes provide a richer, step‑by‑step thinking UI, better state handling during streaming, and expose total thinking duration for downstream components.
