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 — follow-up #1 (mixed
// `$comptime + ..$args` pack-fn signatures).
//
// Today's `isPackFn` rejects pack-fns that mix any other
// comptime param with the trailing pack — they fall through
// to the inline `lowerComptimeCall` path. The inline path
// doesn't bind non-string comptime params as runtime locals,
// so a body that uses both `$tag` (s32) AND `..$args` fails
// at the bare-name lookup of `tag`.
//
// Next commit relaxes `isPackFn` to accept "exactly one
// trailing pack + any number of non-pack comptime params" and
// `monomorphizePackFn` folds the comptime VALUES into the
// mangled name (so distinct calls of `tagged(7, ...)` vs
// `tagged(9, ...)` get distinct monos), then binds the
// comptime values as both comptime substitutions and runtime
// locals (for body code that references them by name).
