selfhost/cmd/ww/main.ww: migrate visitadd strnode amalloc to alloc(T{...})!

Browse Source 
Phase 0 batch 4. Single typed-struct site in the driver. Retires the
32u64 over-size workaround on a 24-byte strnode (selfhost/CLAUDE.md
trap #1 — amalloc < struct corrupts the next slot).

14 other amalloc sites in ww/main.ww are runtime-N path/name buffers
(13 → task #8) and 3 fixed-max ".\0" prefix buffers (→ task #9).
wwdump/main.ww's 1 site is a runtime-N file-size buffer (→ task #8).

Verified 132/132 + 995_self_rebuild byte-identity.
