agra 66bdc70bf1 test: group examples into per-category folders
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.

// First runnable `raise` (ERR step E1.3). A `-> !Named` (pure failable)
// function terminates via the error channel with `raise error.X`; a plain
// `return;` is the success exit (error slot 0). The caller binds the result
// and inspects it with the enum-like `==`. The value-carrying `-> (T, !)`
// shape lands with the error-channel tuple ABI in ERR phase E2.
