…idget - Add stream mode for chains (--stream flag, [v]iew toggle in TUI) - Render subagent messages using AssistantMessageComponent and ToolExecutionComponent from pi-coding-agent for main-chat look - Display thinking blocks with italic thinkingText styling via Markdown - Show tool calls with proper backgrounds, syntax highlighting, and diffs - Add chain status sticky widget with blinking progress indicator - Add 500ms refresh interval to keep widget animation/timer live - Track combined results in interval for running step timer visibility - Extract thinking content blocks in getDisplayItems for chronological display - Add formatToolCallThemed with toolTitle/accent colors matching pi-mono
- Thread expanded state from renderResult options through to inner ToolExecutionComponent instances so ctrl+o toggles expansion - Fix sequential step onUpdate missing streamResults assignment, causing the widget timer to disappear between update callbacks
