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 2 step 2.16c (PLAN-FFI.md): xfail then green for the
// thread-local env fallback in `#jni_call`. When a `#jni_call` site
// has its env arg omitted AND no `#jni_env` block exists in the same
// function (e.g., we're in a helper called FROM such a block), the
// compiler emits a TL load instead of a sema error.
//
// The TL is pushed/popped by the `#jni_env(env) { ... }` enclosing
// scope at runtime; helpers that don't see the lexical scope still
// pick up the env transparently. Cross-function callers no longer
// need to thread env as an explicit parameter.
//
// Today (2.16b only): lowerJniCall errors when env is omitted and
// jni_env_stack is empty, because TL emission isn't wired yet.
#import "modules/std.sx";
g_should_call : bool = false;
// Helper fn — no `#jni_env` block in scope. Without TL fallback this
// errors because the omitted env can't be resolved.
