Inline comments:
In `@rust-toolchain.toml`:
- Line 2: The devnet-curio Dockerfile still pins an old Rust version via the
RUST_VERSION environment variable; update the RUST_VERSION value in
scripts/devnet-curio/curio.dockerfile (the RUST_VERSION environment/ARG line) to
match the rust-toolchain.toml channel ("1.94.0") so the container toolchain
aligns with the repository toolchain.
