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.

// Focused FP-aggregate (HFA) FFI baselines. Distinct from the int-aggregate
// register-coercion paths because all-float / all-double structs of ≤4 fields
// stay as struct values in LLVM and are passed/returned via the float
// register file (AAPCS64 v0..v3; SysV AMD64 xmm0..xmm7). This was the
// `UIEdgeInsets`-as-f32-vs-f64 landmine — pinned here so a future ABI rule
// change that wrecks the FP path fails this test directly.
//
// FQuad — 16 B, four float (small HFA; same slot as Vec4f)
// DQuad — 32 B, four double (UIEdgeInsets-shape HFA)
