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.

// Const aggregates fold at compile time: an array const's `.len` and
// `K[<const idx>]` element reads, and a struct const's field (`LIT.r`),
// are compile-time integer leaves — usable in array dimensions and in
// other constants' initializer expressions, source-aware like every
// const fold.
