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 error-slot discard rejection (ERR step E1.8 — discard slice). The
|
|
// error slot of a value-carrying failable cannot be dropped on a bare
|
|
// destructure: it must be bound (`v, err := …`) and handled, or the failure
|
|
// routed through `try` / `catch` / `or value` (all of which strip the error
|
|
// channel, so they don't reach this check). Two rejected shapes here:
|
|
// (1) omitting the error slot entirely (fewer names than slots), and
|
|
// (2) binding it to `_`.
|
|
// This file is expected to FAIL compilation (exit 1).
