`checkRequiredEntryPoints` no longer accepts `android_main` as an
Android entry — `#jni_main #jni_class("...")` is now the sole accepted
path. The diagnostic walks the user through declaring an Activity +
Bundle foreign decl. `isExportedEntryName` drops `android_main` and
`ANativeActivity_onCreate` (both were for the legacy NativeActivity
glue path R.2 stopped linking by default).
Migrates the two cross-compile examples that previously carried an
`android_main` trampoline to a minimal `#jni_main #jni_class(...) { }`
stub:
- `examples/ffi-jni-call-02-void.sx` — tests `#jni_call(void)` lowering
- `examples/ffi-objc-call-10-os-gate.sx` — tests `inline if OS` gating
Both stubs are empty (no `onCreate` body) so they exercise the
entry-point check + R.3's JNI-symbol synthesis pass produces no
symbols. 131 host / 4 cross / zig build test all green.
`examples/99-android-egl-clear.sx` still uses `android_main` and the
AndroidPlatform/native_app_glue stack — its Android-target build now
fails the entry-point check. R.5 removes it along with the rest of
the legacy NativeActivity surface.

// Phase 1 step 1.14 (PLAN-FFI.md): `#objc_call` inside an
|
|
// `inline if OS == .ios { ... }` arm cross-compiles cleanly to
|
|
// Android. The comptime gate must strip the arm BEFORE the
|
|
// `objc_msg_send` lowering runs, otherwise emit_llvm would
|
|
// produce calls to `@objc_msgSend` / `@sel_registerName` that
|
|
// don't exist in Bionic + libGLESv3 / linker would fail.
|
|
//
|
|
// On macOS the iOS arm is also stripped (we're not iOS) so the
|
|
// runtime test just prints "host stripped both", proving the
|
|
// `inline if OS == { case }` form works around `#objc_call`
|
|
// sites the same way it does elsewhere.
