Release v0.1.31: PipelineLiveFeed Performance Optimization

What changed

• Fixed the scroll-collapse bug: expanding a log row and scrolling away no longer collapses it on scroll back
• Eliminated unnecessary re-renders when new log entries arrive — unrelated rows now stay stable
• Lifted expansion state from individual LogEntryRow components to the parent PipelineLiveFeed using a Map in a useRef
• Wrapped LogEntryRow in React.memo with stable useCallback handlers so React correctly bails out for unchanged rows

Why it matters

With 100+ log rows and entries arriving every second, the old approach caused every visible row to re-render on each new entry — even when that row's data hadn't changed. The new architecture decouples expansion state from component lifecycle so scrolling behavior is predictable, and memoization ensures only affected rows re-render.

Technical notes

Expansion state is now owned by the parent in expandedMapRef (a Map<string, boolean> in a useRef). A lightweight expandedVersion counter triggers just the affected row's re-render when toggled. No breaking changes — behavior is identical from the user's perspective.
