Adapta las recetas importadas a fases hammer (meson/samurai directos, link=dynamic)
y construye+sella la base del stack gráfico para el escritorio tawasuyu:

- samurai: zig 0.13.0 (el default miscompila musl → reallocarray falla en runtime)
- meson:   Python puro, copia mesonbuild/+wrapper (sin wheel/gpep517 que hammer no tiene)
- libdrm:  core-only (GPU helpers disabled) → sin libpciaccess; iris usa libdrm core
- seatd:   libseat.so.1, -Dwerror=false (CMSG_NXTHDR de musl dispara -Wsign-compare)

Pendiente (docs/14-mesa-stack.md §Estado): wayland (los headers de wayland-scanner
no aparecen, prob. libexpat.so en el scanner), wayland-protocols (bloqueada por
wayland) y mesa (la grande, recortada iris-only). meson validado con zig cc sobre
proyectos meson reales (libdrm, seatd).

+| `wayland` | 🟡 **WIP** | falla: `wl_callback_add_listener`/`wl_registry_interface` undeclared → los headers que genera `wayland-scanner` no aparecen. Hipótesis: el scanner (host tool) no encuentra `libexpat.so` al correr durante el build → produce headers vacíos. Probar expat estático o `LD_LIBRARY_PATH` de las deps en la fase. |
+| `wayland-protocols` | ⏸ **bloqueada** | build-depende de wayland (necesita wayland-scanner) |
+| `mesa` | 🟡 **pendiente** | recortar a iris-only (sin LLVM/Vulkan/X11); depende de libdrm✓+wayland+wayland-protocols+expat✓+zlib✓+zstd✓+python3✓+mako(⚪) |

+meson anda con zig cc (clang 21) sobre proyectos meson — validado con libdrm y seatd. El cuello real
+restante es **wayland** (scanner) y luego **mesa**.
