feat: add CircleCI job for building substreams-tron Rust package

- Add dedicated build-substreams-tron job with Rust 1.75 image
- Install wasm32-unknown-unknown target for WebAssembly compilation
- Add cargo caching for faster builds
- Run tests as part of the CI job
- Update package.json to skip lerna build (requires Rust toolchain)
