Research direction
Start by reproducing the example with cargo +nightly -Zscript script.rs and inspect how rust-analyzer handles the shown Rust source and its frontmatter. Done means the example using #!/usr/bin/env cargo, the ---cargo section, and Rust 2024 edition is accepted without the current error.
