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 0 baseline (PLAN-FFI.md step 0.7): `#import c { #include /
// #source }` end-to-end, with the new stdlib-path resolution
// (src/imports.zig added this session). The header + .c live ONLY
// under `library/vendors/sx_ffi_resolve_test/` — not the sx repo
// root vendors/ — so the path can be found only by the stdlib
// search branch (`<exe>/../../library` etc.), not by the CWD or
// importing-file's-dir branches.
//
// `#include` triggers c_import.zig's auto-synthesis of `#foreign`
// fn decls from the C header; `#source` adds the .c to the build's
// object list. Together they let the sx side call the C functions
// by their declared names with no manual decls.
