fix: preserve native thumb geometry while seeking beside it

Remove the knobRect override: native slider geometry also affects drag positioning. Progress pointer tracking now shares the drawn thumb bounds, preserves the initial grab offset, and clamps to the track endpoints. Expanded native event regression covers adjacent clicks, thumb drags, track drags, and endpoint clamping; application build passes.
