Mathias Beaulieu-Duncan 659dade82d perf: Phase 1 critical performance fixes + production macOS build ... Performance: - Move JSON parsing to background isolate via Isolate.run() (eliminates 2-4s UI freeze) - Cache filteredEntries with key-based invalidation (eliminates O(n) recomputation) - Debounce search queries at 300ms (prevents cascade rebuilds on keystroke) - Flatten timeline from 2-level turn×response Column to single virtualized ListView.builder - Add RepaintBoundary per timeline item (isolates repaints during scroll) - Use context.select for granular rebuilds instead of top-level context.watch - Lazy ExpandableCard: child not built until first expand (replaces AnimatedCrossFade) - Use IndexedStack in AppShell (preserves screen state across tab switches) Fixes: - Collect parse errors instead of silently swallowing them - Show parse error count in timeline filter bar - Fix overflow in tokens screen pie chart legend Build: - Configure Developer ID signing with hardened runtime for production distribution - Enable secure timestamps for notarization - Update app name to Claude Session Viewer - Signed, notarized, stapled DMG distribution		2026-04-07 13:32:13 -04:00
