Subject: [PATCH] fix: pin builder to rust:1.77-slim-bookworm to match runtime
 glibc

rust:1.77-slim has drifted to a newer Debian base with glibc 2.39,
but debian:bookworm-slim only has glibc 2.36, causing a GLIBC_2.39
not found error at runtime. Pinning to the explicit bookworm variant
keeps both stages on the same glibc version.
