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: a generic function (with `$T: Type` type params)
// called from inside a pack-fn mono must NOT inherit the outer
// pack maps during its own body lowering. Before the fix landed
// in `monomorphizeFunction`, the cached mono of a generic with
// an `args`-named param had its `args.len` constant-folded to
// the arity of whichever pack shape triggered the first mono;
// every subsequent shape read the same baked-in constant.
//
// Same root cause as issue-0048 (`lazyLowerFunction`), in a
// different lowering path (`monomorphizeFunction`).
