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.

// FFI plan step 5.1 — `build_block_convert(args: []Type, $ret: Type)
// -> string` emits the per-shape source body for the generic
// `Into(Block) for Closure(..$args) -> $R` impl that lands in step
// 5.2. Per-call-shape monomorphisation of the impl body re-runs the
// builder with concrete types bound, so each closure shape gets its
// own dedicated `__invoke` trampoline + Block literal.
//
// This test exercises the builder directly (no `#insert`, no impl
// wiring) — three pack shapes through the same `void`-returning
// wrapper plus one non-void `s32`-returning wrapper to pin the
// `return typed_fn(...)` branch. The expected output captures the
// generated source verbatim so any formatting drift surfaces here
// rather than as a downstream compile error inside the eventual
// step-5.2 impl.
