clearOverlays() cleared this provider's own overlay controllers but not the strategy controller behind MarkerRenderingSupport, so markers drawn by clustering (or any other marker-rendering plugin) stayed on the map. It now ends with MapServiceRegistry.clearMarkerRendering() (ios-sdk-core fix/clear-strategy), which reaches the registered support's clearMarkers(): StrategyMarkerController.clear() (onRemove -> strategy.clear() -> onPostProcess), and the next syncMarkers sends the markers again, as the overlay collectors do after a clear. Requires the ios-sdk-core change that adds clearMarkers() to MarkerRenderingSupport.

なぜ
clearOverlays()は、各プロバイダが自分で持つコントローラ（マーカー・ポリゴンなど）しか clear していませんでした。クラスタリングなどの拡張が登録する Strategy のコントローラ（StrategyMarkerController）は対象外で、clearOverlays()の後もクラスタのマーカーが地図に残っていました。何を変えたか
clearOverlays()の最後でMapServiceRegistry.clearMarkerRendering()（ios-sdk-core の同名 PR で追加）を呼びます。ios-sdk-core 側で
MarkerRenderingSupport.clearMarkers()は既定実装なしの必須要件になります（外部の準拠型はソース互換が壊れます。承認済み）。検証
2026-11-08 に develop（fix/mapview-teardown、fix/geodesic-polygon-fill、fix/clear-followups、refactor/polygon-controller などのマージ後）の上に載せ直してから確かめています。
MarkerRenderingClearTestsを含む。clearMarkers()が何もしないと落ちることを確認済み）。api-surface は追加のみ。clearOverlays()が strategy まで届く経路を、develop の teardown 後のコードで読み直しました（controller → clearOverlaysHandler（MapHost / Coordinator）→ 各コントローラの clear →clearMarkerRendering()。ArcGIS は 3D/2D の controller から、Longdo は OverlayBinding から、OMM はstrategyManager.clearMarkers()を直接）。素通りする経路はありませんでした。fix/overlay-stacking-orderを合わせたアプリを MapLibre / MapKit で動かし、clearOverlays の後に Strategy のマーカー（MarkerClusterGroup 経由）も消えることを確かめました。前回（載せ直す前）は全プロバイダで撮っています。確認できていないもの
.iOS(.v17)にしてビルドと api を確かめました。StrategyMarkerManager.clear()（disconnect）では、GL 以外のプロバイダでネイティブのマーカーが残ります。関連 PR（
fix/clear-strategyの一式）マージの順番:
fix/overlay-stacking-orderの PR 一式とは衝突しません（git merge-treeで確認済み）。順番は clear-strategy → stacking を想定しています。
