agra 4e942b5373 test: migrate examples to XXXX-category-name layout + split expected streams
Rename all example tests/companions to the XXXX-category-test-name scheme
(per-category 100-blocks: basic 0010, types 0100, ... errors 1000,
diagnostics 1100, ffi 1200, ffi-objc 1300, ffi-jni 1400, vectors 1500,
platform 1600). Companions and dir/C fixtures move in lockstep with their
parent test; #import/#source/#include paths rewritten to match.

Expected output now lives in examples/expected/ (a sibling dir of the
tests) split into three streams per the new convention:
  <name>.exit / <name>.stdout / <name>.stderr  (+ optional <name>.ir)

run_examples.sh rewritten: scans examples/ and issues/ for an
expected/<name>.exit marker, captures stdout and stderr separately (no
more 2>&1), compares each stream + exit + optional IR snapshot.

Behavior validated unchanged: every renamed test reproduces its prior
merged output + exit (diffs limited to file paths/basenames embedded in
diagnostics + traces, which correctly reflect the new names). Suite:
292 passed, 0 failed. 50-smoke.sx split + issue relocation + docs follow
in subsequent commits.

// 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.
#import "modules/std.sx";
#import "modules/compiler.sx";
// Empty stub class — Android cross-compile requires a `#jni_main`
// declaration to satisfy the entry-point check. This file is testing
// `inline if OS` gating around `#objc_call`, not Activity wiring.
