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 6 — pack-spread in a parameterized-type's arg list:
|
|
// `Combined($R, ..sources.T)`. Inside a pack-fn, `..sources.T` projects each
|
|
// source's protocol type-arg and spreads them into the generic struct's pack
|
|
// type-param `..$Ts`, so `Combined(i64, ..sources.T)` for a single `VL(i64)`
|
|
// source instantiates `Combined(i64, i64)` (field `sources: (VL(i64))`).
