Completes the invoke→cek-call migration across all spec .sx files: - adapter-sx.sx: map/filter/for-each in aser wire format - adapter-dom.sx: island render update-fn - engine.sx: fetch transform callback - test-cek-reactive.sx: disposal test Only async-invoke (adapter-async.sx) remains — separate async pattern.
