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).
