Subject: [PATCH] Build the module on every pull request
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The parent repository's api-surface.yml only runs on parent pull requests. This
module lives in its own repository, so its own pull requests were never built by
anything.

android-sdk had the same hole: the standalone build was only exercised by the
publish workflow, so it rotted unnoticed and the breakage surfaced on release
day (todo/20260816.txt §8). Add a per-PR build here before the same thing
happens on iOS.

Only modules that need no vendor SDK can run in CI — the providers need
redistribution-restricted SDKs (heresdk, ios-maps-sdk) or a token (Mapbox).
This one depends on MapConductorCore alone.

+# モジュールは独立したリポジトリなので、そちらの PR は誰も検証していなかった。
+# android-sdk では同じ穴が原因で、単体ビルドの設定が腐っていることに

+# ## ここで回せるモジュールの条件

+# ベンダー SDK を必要としないこと。プロバイダの多くは再配布できない SDK
+# （heresdk / ios-maps-sdk）やトークン（Mapbox）が要るので CI では組めない。
+# このモジュールは MapConductorCore にしか依存しないので回せる。
