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.

// Module B authors a same-name `Box` shadow whose field SELF-REFERENCES its own
// name (`next: *Box`). Pre-fix the self-ref resolved to A's `Box` (registered
// first under the bare name), so `next.*.y` failed with "field 'y' not found on
// type 'Box'". The shadow's slot is now reserved BEFORE its fields resolve, so
// `*Box` binds to B's OWN nominal TypeId and the deref sees B's `y`.
Box :: struct { y: i64; next: *Box; }
b_chain :: () -> i64 {
tail := Box.{ y = 42, next = null };
head := Box.{ y = 1, next = @tail };
// Walk the self-referential link; reads B's own `y`, not A's `x`.
return head.next.*.y;
