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.

// Phase 1 step 1.6 (PLAN-FFI.md): non-void return shapes through
