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.

// Pre-fix: `resolveType(null)` silently returned `.s64`, so a top-level
// var without a type annotation got typed as `s64` regardless of what
// the initializer was. For `g_pi := 3.14;` this meant the float literal
// was assigned to an s64 slot, producing a wrong value at runtime or
// the wrong codegen shape.
//
// After the fix `lowerVarDecl` at the top level mirrors the local-scope
// path: explicit annotation → resolveType; no annotation → infer from
// the initializer's type. Mirrors how `:=` already worked for locals.
#import "modules/std.sx";
g_count := 42; // inferred s64
g_pi := 3.14; // inferred f64 — used to silently become s64
g_flag := true; // inferred bool
main :: () -> s32 {
print("count = {}\n", g_count);
print("pi = {}\n", g_pi);
print("flag = {}\n", g_flag);
return 0;
