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.

// M1.2 A.4 — class-pair registration with the Obj-C runtime.
//
// Every sx-defined '#objc_class' produces a module-init constructor
// (registered in '@llvm.global_ctors' AND injected at the top of
// 'main' for the ORC JIT path) that calls:
//
// super = objc_getClass("NSObject")
// cls = objc_allocateClassPair(super, "SxFoo", 0)
// objc_registerClassPair(cls)
//
// After the constructor runs, 'objc_getClass("SxFoo")' returns the
// freshly registered class — the round-trip we verify below.
//
// Methods, the '__sx_state' ivar, and the '+alloc' / '-dealloc'
// overrides land in A.4b / A.5 / A.6; this slice just makes the
// class EXIST in the runtime.
