fix(ci): prevent v8/musl build failures in artifacts and Docker

[hubcio]

charming's "ssr" feature pulls deno_core -> rusty_v8, which
has no prebuilt static libraries for any musl target. The
bench-dashboard exclusion only covered aarch64-musl, leaving
x86_64-musl broken after #2833 added the ssr feature.

Extend the musl exclusion to all musl targets in the artifact
build. Scope each Dockerfile's cargo-chef cook to only the
packages it ships (-p), avoiding workspace-wide feature
unification that drags in v8 for images that never use it.
