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.
The plan producer's namespace-fn arms returned the declared return type
without checking type_params, so a qualified generic call's result
carried the unbound T stub: print boxed it as 'T{}', and a non-s64
binding failed LLVM verification (pack monomorphized for the stub,
call returning double). Both fn_ast_map-backed arms now classify
generic callees as generic_fn and infer the return through
inferGenericReturnType, mirroring the bare-identifier path.
