agra 2888f6fc00 refactor(ffi-linkage): Phase 7.3 — migrate 14xx ffi-jni examples #foreign→extern
13 JNI examples migrated (1410-1419/1423/1424/1425): import runtime classes
'#foreign #jni_class("X") {' → '#jni_class("X") extern {'. 1417 (all-runtimes)
also exercises #jni_interface/#objc_class/#objc_protocol/#swift_class/#swift_struct/
#swift_protocol — all take the postfix modifier (verified by probe), migrated via a
generalized '#foreign #<directive>("X") {' → '… extern {' rewrite. No 14xx snapshot
asserts on 'foreign'; empty snapshot diff, corpus-validated.

KEPT comment-only #foreign in 1426 (jni-extern-class test, no decls). Suite green
(647 corpus / 444 unit, 0 failed).

// `super.method(args)` dispatch inside a `#jni_main` Activity body
// (chess-on-Pixel migration, R.6). The override of a lifecycle method
// like `onCreate` needs to invoke the parent's `onCreate` so the
// Android runtime's setup completes (`SuperNotCalledException`
// otherwise) — the sx-side body calls `super.onCreate(b)` and the
// compiler lowers it to JNI `CallNonvirtualVoidMethod` against the
// parent class declared via `#extends`.
//
// No `#extends` here → defaults to `android.app.Activity`. The smoke
// is compile-only — runtime correctness is verified by APK install
// + on-device launch, which is the chess deploy.
