Summary: Adds the `enableMountingCoordinatorPullModelAndroid` experiment flag (default off) that gates the Android pull-model mounting migration. Config entry plus regenerated accessors only — no behavior change. ## Changelog: [Android] [Added] - Add `enableMountingCoordinatorPullModelAndroid` feature flag Differential Revision: D112309049
Summary: Java side of the pull model — dead code until the C++ wiring lands: - `PullTransactionMountItem`: asks C++ (via `FabricUIManagerBinding.pullAndExecuteTransaction`) to pull the surface's pending transaction and apply it synchronously on the UI thread. - `FabricUIManager.onTransactionAvailable` (JNI entry): enqueues a `PullTransactionMountItem`. - `FabricUIManagerBinding.pullAndExecuteTransaction`: extern declaration. One item is enqueued per notification, mirroring iOS; redundant items no-op in C++. ## Changelog: [Android] [Added] - Add inert Java plumbing (`PullTransactionMountItem`, `FabricUIManager.onTransactionAvailable`) for the pull model Differential Revision: D112309050

Summary: Pull Request resolved: #57579 Makes `enableMountingCoordinatorPullModelAndroid` functional. With the flag on, the commit thread only signals transaction availability and the UI thread pulls and applies at mount time (matching iOS/macOS); with the flag off (default), behavior is byte-for-byte identical. - `schedulerShouldRenderTransactions`: notifies via JNI (`FabricMountingManager::onTransactionAvailable`) instead of pulling and building the batch. - `schedulerDidFinishTransaction`: no-op under the pull model. - `FabricUIManagerBinding::pullAndExecuteTransaction` (new JNI method): pulls the surface's transaction on the UI thread and runs `executeMount`. - `FabricMountingManager::executeMount`: gains a `synchronous` mode that executes the batch directly on the UI thread. - The accumulation sites remain gated on `enableAccumulatedUpdatesInRawPropsAndroid`; the pull model requires that flag to be co-enabled, since a pull may collapse several commits into one diff and therefore needs complete accumulated rawProps. ## Changelog: [Android] [Added] - Wire the pull-model mounting path in C++ behind `enableMountingCoordinatorPullModelAndroid` Differential Revision: D112309053
