- Remove redundant console.log in cli.ts (already logged via logger.fatal)
- Remove duplicate Canvas useEffect that called draw() on every change
- Use hoveredNodeRef instead of state in draw() to avoid recreation on mouse move

- Only update event log state when lengths actually change
- Only update animatedTxs state when count changes

These changes prevent the force layout from triggering 100+ React
re-renders per second during initial settling.
