Developer's checklist

• My PR follows the style guidelines of this project
• I have performed a self-check on my work

If changes are made in the code:

• I have followed the Coding Guidelines
• My changes in code generate no new warnings
• My changes are not breaking another fix/feature of the project
• I have added test cases to show that my feature works
• I have added relevant screenshots in my PR
• There are no UI/UX issues

Please rebase your PR branch onto the latest develop (do not merge develop into your feature branch).

Try:

git fetch upstream
git rebase upstream/develop

Resolve conflicts and run local checks (npm run lint, npm run build)
git push --force-with-lease origin <your-branch>

Notes:
No need to fix unrelated pre-existing warnings.
Do fix errors introduced by your PR (especially in touched files).
This rebases only your PR branch; it does not rewrite our develop branch.

@GauravKarakoti
Add try/catch around localStorage, so JSON parsing to handle invalid/corrupted stored data safely.

Prefer using tool url as the favorite identifier instead of title to avoid key collisions.

Add an aria-label on the star toggle button for accessibility.

Thanks @GauravKarakoti , the requested fixes are implemented: localStorage parse safety, URL-based favorite keying, and aria-label on the star toggle.

One process issue remains:
This branch includes a merge commit from develop (a877006). Please rebase onto latest develop and force-push with --force-with-lease (no merge commit).
Also please drop unrelated package-lock.json changes unless there is an intentional dependency update.

I suggest to raise a fresh PR so its easy to re-review and safely merge to develop!

Closing this PR for now :)
