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).

// `Alias.new(args)` constructor dispatch on a `extern #jni_class`
|
|
// (chess-on-Pixel migration, R.6). The sx-side `static new :: (...) ->
|
|
// *Self;` member lowers to JNI `FindClass + GetMethodID("<init>", sig)
|
|
// + NewObject(env, clazz, mid, args...)`.
|
|
//
|
|
// This smoke instantiates a `SurfaceView` from inside the Activity's
|
|
// `onCreate` body — chess's render surface starts the same way.
