feat(core/hooks): add 'useThrottledCallback' hook

[sukvvon]

Overview

Completes the useThrottle/useThrottledCallback pair, matching the existing useDebounce/useDebouncedCallback pattern.

Note: onChange is currently boolean-only, matching useDebouncedCallback's current API. PR #267 extends useDebouncedCallback to generic <T> — after that merges, a follow-up to make useThrottledCallback generic as well would be welcome.

LGTM!

@kimyouknow Hi! I noticed that the merge commit (b94ff72) for #342 has you as the Author instead of me. It looks like this PR was merged with a merge commit instead of squash merge. With a regular merge, the merge commit's Author is set to whoever clicked the "Merge" button. Other PRs like #339 were squash-merged, so the Author correctly reflects the PR author. Could this be re-done with squash merge, or is there a way to fix the Author?

Hi @sukvvon, just a heads-up: when I merged this PR, the merge commit was incorrectly attributed to me instead of you due to a non-squash merge. I've fixed this by squashing the commits and force-pushing to main — your authorship is now correctly reflected. Sorry for the confusion!
