Newest published aether. 0.645 adds a lint (warn on `malloc(<literal>) as *T`,
the layout-corruption pattern 0.643 fixed) — a purely additive diagnostic, no
grammar/API/primitive change aeb needs; the floor moves with FETCH per the
no-back-compat DSL policy. Verified against the real 0.645.0 linux tarball: aeb
builds clean, full suite 134/134; glibc floor GLIBC_2.34 (Debian-12 safe); all
platform assets published.
