[Copilot]

The debounce delay should be extracted as a constant at the class or companion object level, or made configurable, rather than being a magic number in the property declaration.

Suggested change

	private val debounceDelay = 500L // 500ms debounce delay
	companion object {
	const val DEBOUNCE_DELAY = 500L // 500ms debounce delay
	}
