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 — pack spread into a call's positional arguments. `f(..xs.get)`

// projects `get` over the pack and spreads the resulting tuple into f's params:

// add2(..xs.get) ≈ add2(xs[0].get(), xs[1].get())
|

// The canonical's `mapper(..sources.value)` is this shape.
