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.

// Comptime return-trace resolution (ERR E3.0 slice 3b). A `#run` block that
// raises, propagates via `try`, and catches the error, then formats the trace
// with `trace.print_current()`. At comptime a frame is a packed
// `(func_id, span.start)` (not a `*Frame`); the interpreter's `.trace_resolve`
// unpacks it and resolves `file:line:col` via the module + source map — so the
// comptime trace prints the same `func at file:line:col` form as a runtime one.
// Expected exit: 0 (the error is caught; the trace is printed during the build).
