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.

// Inferred-set widening rejection (ERR step E1.4b). When a named caller

// (`-> !A`) `try`s a bare-`!` callee, the callee's WHOLE-PROGRAM-CONVERGED
|

// inferred set must be a subset of A. Before the SCC pass this was a
|
|
// false-negative (the bare-`!` placeholder was empty, so the check trivially
|
|
// passed); now the converged tags are checked. `deep`'s converged set is
|

// {Foo} (raised transitively through `via`), which is not in A = {Bar}.
