fix(container): copy crates/ + benches/ in minimal & full Containerfiles

The workspace Cargo.toml declares path-deps crates/echidna-core and
crates/typed_wasm plus crates/* workspace members. The minimal
.containerization/Containerfile and Containerfile.full copied only
src/rust + src/interfaces, so the rust-builder stage failed:

  error: failed to load manifest for workspace member
  /build/crates/echidna-core/Cargo.toml — No such file or directory

This is the same omission Containerfile.wave3 already fixed in this PR;
carry the identical COPY crates/ (+ benches/) to the other two
Containerfiles so 'Build & verify container image' (ghcr-publish.yml,
which builds the minimal Containerfile) goes green. Containerfile.mcp
already had it.
