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.

// Regression: new-form variadic `..name: []T` defined in an imported
// module is callable from another module without crashing LLVM emit.
//
// Before the fix in `resolveParamType` + `packVariadicCallArgs`,
// the new-form variadic's element type went through one extra
// `sliceOf` wrap (the helpers treated `..parts: []string` the same
// as the legacy `parts: ..string` and added a slice level on top
// of the already-declared slice). The double-wrapped `[][]T`
// signature mismatched what the call-site marshalling emitted as
// `[N x T]`, producing null/undef Refs that crashed
// `LLVMBuildExtractValue` inside `emitStrCmp` during emission.
//
// Today's stdlib `path_join` uses the new form
// (`(..parts: []string) -> string`); it lives in `modules/std.sx`
// and is called here from the test module. Two- and three-arg
// shapes must round-trip the slice through the function-call
// boundary and concatenate the parts with '/'. Empty join (no
// args) returns "".
#import "modules/std.sx";
