## FRONTEND: Add `useDebounce` Hook for Search Inputs

[OSEH-svg]

Description
The Discover page and future search inputs trigger API calls on every keystroke. Issue #720 called for debounced search and was closed, but the hooks/ directory contains no useDebounce.ts file. The hook was never actually added to the repository.

Tasks

• Create hooks/useDebounce.ts with a generic useDebounce<T>(value: T, delay: number): T implementation.
• Apply it to the search input on the Discover page.
• Add a unit test in __tests__/use-debounce.test.ts.
  Acceptance Criteria
• hooks/useDebounce.ts exists and exports the hook.
• The Discover page search input debounces API calls at 300ms.
• Unit test covers: value updates before delay (should not change), value updates after delay (should change).

I'll take this. Creating hooks/useDebounce.ts with a generic useDebounce(value: T, delay: number): T implementation, wiring it into the Discover page's search input at 300ms, and adding a unit test in tests/use-debounce.test.ts covering both cases: value doesn't change before the delay fires, value does change after.
