* fix: correct interleaved streaming order (Text → Thinking → Tool → Text)
During live streaming, tool cards were inserted before their associated
thinking cards instead of after them. The root cause was that
appendLiveToolCard's anchor selector didn't include .thinking-card-row,
so finalized thinking cards were skipped when finding the insertion point.
Changes:
- messages.js: Add segment splitting (segmentStart/_freshSegment) so each
text segment after a tool call renders only its own slice, not the full
accumulated text. Sync thinking card render in reasoning handler to
avoid rAF race with tool events. Guard removeThinking() to preserve
finalized cards when reasoningText is active.
- ui.js: Add .thinking-card-row to appendLiveToolCard anchor selector so
tool cards land after finalized thinking. Add anchor-based positioning
to appendThinking for correct interleaved placement. Clean up empty
spinner-only thinking rows in finalizeThinkingCard. Add 3-dot waiting
indicator (toolRunningRow) after tool cards for visual feedback.
- style.css: Scope blinking cursor to last live-assistant segment only.
Add spacing for toolRunningRow.
* chore: CHANGELOG for v0.50.174
