…facebook#54791) Summary: This change adds a listener mechanism to the `OverrideColorScheme` interface to enable dynamic updates when the user's dark mode preference changes via `OverrideColorScheme`. Previously, `AppearanceModule` would only reflect the initial color scheme state when instantiated. If a user toggled dark mode through an `OverrideColorScheme` implementation, React Native JavaScript would not be notified of the change, causing UI inconsistencies. This implementation adds: 1. An optional `addSchemeChangeListener()` method to the `OverrideColorScheme` interface with a default no-op implementation for backward compatibility. Also adding matching `removeSchemeChangeListener()`. 2. Automatic listener registration in `AppearanceModule`'s init block that triggers `onConfigurationChanged()` when the color scheme changes Changelog: [Android][Added] - Add `addSchemeChangeListener()` function to `OverrideColorScheme` interface to support dynamic appearance updates via override Reviewed By: mdvacca Differential Revision: D88427482
