* refactor: use Immer for immutable state updates
Replace Set/Map with Record types and use Immer's produce() for
immutable state updates. This fixes mutation bugs where .add()/.set()
were mutating state before copying (e.g., `new Set(prev.add(id))`).
Changes:
- Add immer dependency
- Convert Set<string> to Record<string, true> (sparse hash set pattern)
- Convert Map<K,V> to Record<K,V>
- Use produce() for all state mutations
- Update prop types in child components
