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).

// `#jni_main` pipeline slice 2 (PLAN-FFI.md): the compiler renders a
|
|
// `.java` source for a `#jni_main #jni_class("...")` declaration, runs
|
|
// `javac` + `d8`, and bundles `classes.dex` into the APK.
|
|
//
|
|
// Slice 2 only wires the plumbing — the manifest still points at
|
|
// `android.app.NativeActivity`, so the user's class isn't loaded at
|
|
// runtime. Slice 3 (manifest synthesis) and slice 4 (RegisterNatives)
|
|
// land in follow-up commits.
