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.

// `#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.
//
// Build to inspect APK contents (requires Android SDK + JDK):
// /Users/agra/projects/sx/zig-out/bin/sx build --target android \
// --apk /tmp/sxjnimain.apk --bundle-id co.swipelab.sxjnimain \
// -o /tmp/libsxjnimain.so examples/ffi-jni-main-01-emit.sx
// unzip -l /tmp/sxjnimain.apk | grep classes.dex
#import "modules/std.sx";
#import "modules/compiler.sx";
// `*Bundle` resolves through the class registry to `android.os.Bundle`
// in the emitted Java — needed for `onCreate`'s @Override to match
// NativeActivity's superclass signature.
Bundle :: #foreign #jni_class("android/os/Bundle") { }
// `#jni_main` flags this as the launchable Android Activity class. The
// `onCreate` body is empty for now — slice 4 wires `RegisterNatives`
// so the `sx_onCreate` native delegate actually binds to a sx-side fn.
