test: migrate examples to XXXX-category-name layout + split expected streams

Browse Source 
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 0 baseline (PLAN-FFI.md step 0.4): focused FP-aggregate (HFA)
// FFI test. All-float / all-double aggregates of ≤4 fields stay as
// struct values in LLVM and pass through the float register file
// (AAPCS64 v0..v3, SysV AMD64 xmm0..xmm7). Distinct from the int
// register-coercion paths (i64 / [2 x i64]).
//
// FQuad — 16 B, four f32 (same slot as ffi-02's Vec4f)
// DQuad — 32 B, four f64 (UIEdgeInsets-shape HFA — the
// f32-vs-f64 landmine from this session)
//
// Already nominally covered by ffi-02's Vec4f, but pinning it as a
// focused single-file test means a future ABI rule change that
// breaks the FP path fails *this* test directly without a noisy
// drag-in from the multi-shape baseline.
