`cargo install cargo-chef --locked` will not install on rust < 1.88 for versions > 0.1.74

Nobody has claimed this yet.

The edition flag in `cargo-chef` is still 2018. However, there are dependencies which are no longer compatible with edition 2018 (specifically `cargo-platform`). The version of that dependency should be locked to maintain this crate's ability to be installed on 2018 toolchains, or the edition flag bumped to reflect reality.

I know rust 1.86 is long in the tooth now, and we can install v0.1.75 which still compiles, but this is more about just ensuring that the metadata is aligned with reality. Thanks!

Caused by:
rustc 1.86.0 is not supported by the following package:
cargo-platform@0.3.2 requires rustc 1.88
```

Reproduce the failure with `cargo install cargo-chef --locked` on Rust 1.86. Inspect cargo-chef's dependency metadata and locked dependency versions, focusing on cargo-platform and the crate's stated edition. Done means versions above 0.1.74 can install on the supported 2018 toolchains while the metadata accurately reflects compatibility.
