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.

// Feature 1 — a pack element exposes ONLY the constraint protocol's interface.

// `xs[i].v` reaches a concrete field of IntCell that is not part of `Box`, so
|
|
// it's rejected even though IntCell does have `v` — a pack element is viewed
|
|
// through the protocol, like a constrained generic. (Protocol methods like
|
|
// `get()` ARE callable; see examples 193/194.)
