Proposal for Extensible Cargo Runner Configuration

[codeitlikemiley]

As Rust continues to grow and more frameworks emerge, it becomes increasingly challenging to produce a unique configuration for each one. The purpose of this pull request (PR) is to enable users to create extensions for the Cargo runner, allowing them to develop their configurations, run tests, and share their setups with the community.

Future Enhancements

In future releases, we envision adding the capability to generate predefined configurations, such as:

• Default (using Cargo)
• Leptos
• Dioxus
• Etc.

Each project or workspace would have its own predefined configuration, eliminating the need to manually modify settings for each new crate.
