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.

// M1.2 A.1 follow-up — pass-by-value struct args/returns in
// sx-defined `#objc_class` methods.
//
// Wires the new `{Name=field0field1...}` arm of
// `appendObjcEncoding` into `class_addMethod` registration. Without
// it, methods that take or return a value-type struct (CGPoint,
// CGSize, NSRange shapes) used to fail signature-encoding
// derivation with a "type kind not yet supported" diagnostic.
//
// Each sx-defined method registered with the Obj-C runtime needs an
// encoding string built from its IR signature. For
// `goto :: (self: *Self, p: Point)` that string is `v@:{Point=dd}`
// — return void, receiver `@`, selector `:`, then the struct
// argument `{Point=dd}`.
//
// We don't observe the encoding string directly here (it ends up in
// a private OBJC_METH_VAR_TYPE_ cstring in the linked binary) — but
// the compiler bails LOUDLY on unsupported types per the project's
// REJECTED PATTERNS rule, so a successful build is the encoding
// going through cleanly.
