[PERF] Memoize expensive Toolkit filtering and grouping

[utksh1]

Summary

Toolkit filtering/grouping should avoid unnecessary recomputation as the catalog grows.

Scope

• Audit Toolkit derived arrays and grouping logic.
• Use useMemo where it materially reduces repeated work.
• Keep behavior and rendered output unchanged.

Acceptance Criteria

• No visual behavior changes.
• Add or update tests if the refactor touches filtering semantics.
• Avoid premature abstractions beyond the Toolkit page.

Hi @utksh1 👋

I would like to work on this issue under GSSoC'26.

I will audit the Toolkit filtering and grouping logic to identify unnecessary recomputations and optimize them using useMemo where it meaningfully improves performance. I’ll ensure:

• No changes to existing UI behavior or rendered output
• Clean and maintainable optimization without over-abstraction
• Stable filtering/grouping semantics
• Proper test updates if any filtering logic is touched during refactoring

I’ll keep the implementation lightweight, readable, and aligned with the current frontend architecture.

Please assign this issue to me. 🚀
