Primera tanda del rollout aprobado. harkaq nombró 47 recetas compiler=gcc;
migra-zig.sh midió que las C-puras migran a zig (~85%). Estas 11 se verificaron
en el LAPTOP (store completo, fiable): construyen con zig-cc Y —las que tienen
binario— corren limpio.

  bzip2 expat json-c gzip htop less libpng libyaml zstd libffi xz

El compiler=gcc era deuda histórica: se marcaron con zig 0.13/0.16 (que
segfaultaban C clásicos), zig mejoró, el gcc quedó por inercia. Verificado
in-place: bzip2→b3:86a33b76, json-c→b3:9cbe76e3.

11 dependencias menos del gcc de Alpine. Quedan ~25 C-puras candidatas del VPS
por verificar en el laptop (el store parcial del VPS daba build-falla espurios
por deps faltantes — la medición fiable es la del laptop) + las 11 Rust
(sys-crate C, otra evaluación).

OJO: re-hashea estas 11 (estaban en el índice firmado 748); el índice necesita
re-firma en el próximo packaging.
