feat: optimize re-renders for builder-component

[midhunadarvin]

Description

• prevent updateState calls whenever we call delete key on the rootState

[!NOTE] Introduce onChange.suspend/resume and use them to batch rootState resets in BuilderComponent, reducing unnecessary re-renders.

• State change tracking (packages/react/lib/on-change.js):
  • Add SUSPEND/RESUME symbols and isSuspended flag.
  • Expose onChange.suspend(proxy) and onChange.resume(proxy) APIs.
  • ignoreChange now skips notifications while suspended; handler exposes suspend/resume at root.
• Builder component (packages/react/src/components/builder-component.component.tsx):
  • Wrap builder.resetState and builder.resetSymbolState handlers with onChange.suspend(this.rootState)/onChange.resume(this.rootState) to batch deletions/assignments.
  • After reset, call debouncedUpdateState (1s debounce) to coalesce updates.
  • Add debouncedUpdateState = debounce(this.updateState, 1000).
