• New outputs nzBlur and nzFocus have been introduced here. Consider adding tests to verify that these events are emitted correctly on blur and focus actions.

readonly nzBlur = output<void>();

components/input-number/input-number.component.ts:306

• The conditional logic has been inverted to emit nzFocus on a truthy 'origin' and nzBlur on a falsy 'origin'. Please confirm that this change accurately reflects the intended focus and blur behavior.

在 v19 我们将旧版 NzInputNumberModule 标记为弃用，在 v20 之前我想我们需要使新版组件与旧版在能力上对齐，并且足够稳定，所以我将此 PR 放到 v19.3 milestone 中。
另外，我认为需要给足够的时间使其完全迁移，旧版组件我建议在 v21 中移除。
