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 1.3 (PLAN-FFI.md): smallest end-to-end `#objc_call`.
// Void return, nil receiver — Obj-C runtime guarantees that messages
// to nil are no-ops with a zero result, so we don't need to set up
// a real object graph to exercise the lowering surface.
//
// Today (step 1.3, test-add): codegen rejects the FfiIntrinsicCall
// AST node. Snapshot pins the failure mode.
// Next (step 1.3, make-green): emit_llvm.zig synthesizes
// %sel = call ptr @sel_registerName(ptr @"sel:init")
// call void @objc_msgSend(ptr null, ptr %sel)
// per call site (no selector interning until step 1.5).
