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 `try` (ERR step E1.4a). The STANDALONE form: a failable
|
|
// expression whose failure propagates to the enclosing function's error
|
|
// return (Zig-style). `outer` calls `try inner(n)` — on `inner`'s failure
|
|
// `outer` returns that error; on success it continues. Both are pure
|
|
// failable (`-> !E`). The error-channel tuple ABI for value-carrying
|
|
// `-> (T, !)` and `try` in an `or` chain land in ERR E1.4b/E2.
