Fix resolved comment highlights not disappearing immediately

The resolve-thread socket event was only handled in ReviewPanel's
useEffect, but ReviewPanel is conditionally mounted (only when visible).
When Claude Code resolves a comment via MCP with the panel hidden, the
resolvedThreadIds store was never updated, so the editor highlight
persisted until the user opened the Review panel.

Fix: add a comments:event listener in App.tsx (always mounted) that
updates resolvedThreadIds for resolve/reopen/delete-thread events.
