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.

// Comptime type construction — channel result types: RecvResult($T) /
|
|
// TryResult($T), built ENTIRELY in sx library code as type-fns over the
|
|
// `define(declare(), ...)` primitives (no compiler machinery). A blocking recv
|
|
// yields a value or a `closed` marker; a non-blocking try-recv adds `empty` —
|
|
// three states a bool can't express. This locks that they construct and match
|
|
// like any enum, and that `RecvResult(i64)` is one nominal type across sites
|
|
// (the type-fn identity path).
