chore: avoid multiple rustup installation (#1571)

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

* **Chores**
* Updated build configuration to account for Rust/Cargo toolchain
changes, ensuring WASM-related builds automatically re-run when the
toolchain updates.
* Standardized repository configuration to the latest schema for
improved compatibility.
* Added an internal script to surface the Rust/Cargo version for build
orchestration.
  
No user-facing behavior changes; these updates improve build reliability
and consistency across environments.

This is used to avoid downloading Rust toolchain in parallel, which
could cause error.

See:
https://github.com/lynx-family/lynx-stack/actions/runs/17091970609/job/48467545202?pr=1569

> [!NOTE]
> We would run `turbo build` first on CI. And if no cache hit for `cargo
build` tasks, we would setup Rust toolchain and re-run build again.
>
> But this is a little different with the Windows runner. Since there
are `cargo` and `rustup` on the Windows runner, we would start
downloading Rust toolchain in parallel in the first `turbo build`.
