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).

// Phase 2 step 2.6 (PLAN-FFI.md): xfail then green for the
// `#jni_method_descriptor("(Sig)Ret")` per-method JNI-descriptor
// override.
//
// The default descriptor is derived from sx types (Phase 2.8); this
// directive is the escape hatch when the auto-derived signature
// doesn't match (e.g., synthetic methods, ambiguous overloads,
// accessing JNI internals). It appears trailing the method's return
// type, before the terminating `;`.
