agra 66bdc70bf1 test: group examples into per-category folders
Move examples/*.sx and their expected/ snapshots into per-category
subfolders (examples/<category>/...). Folder = leading filename token,
with ffi-objc/ffi-jni kept whole; filenames are unchanged. The corpus
runner and LSP sweep now discover each category's expected/ dir, while
issues/ stays flat. Example 1058's repo-root-relative companion import
is made file-relative. Path strings embedded in 164 snapshots were
regenerated (path-only changes). Test-layout docs in CLAUDE.md updated.

// Caller-owned helpers passed as VARIADIC comptime-pack args (`..$args`) to a
// NAMESPACED imported metaprogram resolve in the CALLER's visibility context —
// not the metaprogram's defining module (regression, issue 0106 follow-up).
//
// `std.print :: ($fmt: string, ..$args)` is authored in `std.sx`; the pack args
// `caller_num()` / `caller_two()` are authored HERE in the caller. The body's
// typed `args[i]` substitution (via packArgNodeAt) lowers each pack arg under
// the metaprogram's defining-module pin, so without stamping the pack-arg nodes
// with the caller's source, the bare names `caller_num` / `caller_two` were
// wrongly checked against `std.sx` and rejected as "not visible". The fixed
// comptime param (`$fmt`) already got this treatment; this extends it to every
// node in the variadic pack. The metaprogram's OWN code (build_format / out)
// still resolves in `std.sx`, so the defining-context pin stays intact.
//
// Two pack positions lock that EVERY pack arg is stamped, not just the first.
// i64 values only — accepted by print at runtime today (no 0107/0108 coupling).
