Description

Androidx Fragment 通过Add() Hide() 方式实现懒加载

在调用 add 或 show 方法后，setMaxLifecycle(showFragment, Lifecycle.State.RESUMED)

在调用 hide 方法后，setMaxLifecycle(fragment, Lifecycle.State.STARTED)

建议 增加fragmentTransaction.setMaxLifecycle 支持

Contributor guide

Research direction
Investigate the existing FragmentUtils implementation to identify where `add()` and `hide()` are used, then add `setMaxLifecycle()` calls to enforce lazy loading: `setMaxLifecycle(showFragment, Lifecycle.State.RESUMED)` after show/add, and `setMaxLifecycle(fragment, Lifecycle.State.STARTED)` after hide.
