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.

// Failable calls in cleanup bodies must be absorbed locally (ERR step E1.7). A

// `defer` / `onfail` body runs while the block is already exiting, so a failable

// it calls has nowhere to propagate — it must be handled in place with `catch`
|

// or an `or <value>` terminator. This file shows the accepted forms; the bare
