##### What's Changed

- Use `CARGO_BUILD_WARNINGS` for enforcing warning free compilations
([#&#8203;98](https://redirect.github.com/actions-rust-lang/setup-rust-toolchain/issues/98))
This is a new variable supported by cargo 1.97+ [and sets the
`build.warnings`
config](https://blog.rust-lang.org/2026/07/09/Rust-1.97.0/#cargo-support-for-denying-warnings).
It allows removing the `RUSTFLAGS="-D warnings"` default, which will
improve compatibility with `target.*.rustflags` and `.cargo/config.toml`
files.

This adds a new `build-warnings` input to configure the value for the
`build.warnings` config.
- Add error matcher for Rust panics
  This will highlight the location of the panic location during tests.
- Reuse output of `rustc --version --verbose` calls
