Current evaluation

Cargo-use lacks the disable-parallel part property; the maintainer marked it Needs information and is waiting for a real-world Rust build that fails with parallel execution.

Suggested action: keep open

Reason: This is a valid, clearly scoped enhancement, but the maintainer explicitly describes it as extremely low priority until a real-world failure case is provided. The Status: Needs information label and lack of follow-up indicate it is awaiting more evidence, while CargoUsePluginProperties still lacks disable_parallel and the cited Autotools change provides a relevant implementation pattern.

Issue body

### What needs to get done Support the [disable-parallel](https://canonical-craft-parts.readthedocs-hosted.com/latest/common/craft-parts/reference/part_properties/#disable-parallel) part property in the cargo-use plugin. ### Why it needs to get done All of our plugins should theoretically support this. In practice though, this is extremely low priority until someone shows us a real-world use case for it. If someone can bring us a real-world use case that we can test against (especially a case of "this application simply does not build with parallel"), that would be ideal. The [autotools plugin](https://github.com/canonical/craft-parts/pull/1167) required this for OpenJDK builds, for example.
