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 4.2 — parameterized protocol as a runtime VALUE type. `VL(i64)` is a
|
|
// 16-byte protocol value {ctx, vtable} (a plain protocol was already, but a
|
|
// parameterized one used to resolve to a 0-field stub). A conforming struct
|
|
// `xx`-erases into it, and method dispatch uses the bound type-arg
|
|
// (`get -> T` becomes `get -> i64` for `VL(i64)`).
