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.

// Variadic heterogeneous type packs — `..$args` — type-system
// representation lock-in.
//
// Step 1c slice for the pack feature (see
// ~/.claude/plans/lets-see-options-for-merry-dijkstra.md). Exercises
// the parser's acceptance of `..$args` inside a `Closure(...)` type
// expression — the pack-shape spelling used by impl headers like
// `impl Into(Block) for Closure(..$args) -> $R`.
//
// Today's parser only accepts `..$args` in fn parameter lists (1b);
// the same syntax inside a `Closure(...)` type expression hits
// `expected type name` at the `..` token. This file pins that
// rejection. The next commit teaches `parseTypeExpr`'s `Closure(...)`
// arm + the type-table representation to carry the pack.
