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 1.22 (PLAN-FFI.md): `#jni_call(*void)` (jobject
// return). Last return-type variant in the matrix. The returned
// jobject is a JNI LocalRef — its lifetime is bounded by the native
// frame, so chains of calls within one frame don't need explicit
// cleanup, but calls that escape (cached cross-frame) should be
// promoted via `NewGlobalRef`. For chess Android use the returned
// jobject is consumed inline by the next `#jni_call`, so no cleanup
// is needed here.
//
// CallObjectMethod lives at vtable slot 34.
