test: e2e

[fmorency]

This pull request introduces a comprehensive end-to-end (E2E) testing framework for the converter contract, modernizes the build process, and improves project configuration and maintainability. The most significant changes are the addition of E2E tests using Dockerized environments and Bats, streamlining of WASM build and optimization, and several updates to Rust toolchain and workflow automation.

End-to-End Testing Infrastructure:

• Added a full E2E test suite using Bats, including test scripts (e2e/tests/converter.bats), helper functions (e2e/test_helper/common.sh), and Bats assertion libraries as submodules. Tests are run in a Docker Compose environment simulating a blockchain ledger, with all necessary environment variables and scripts for chain initialization. [1] [2] [3] [4] [5] [6] [7] [8]

• Introduced a new e2e job in the GitHub Actions CI workflow to automate E2E testing, including installation of dependencies and orchestration of the test environment.

Build and Workflow Improvements:

• Refactored WASM build and optimization steps to use a new build-opt target in the Makefile, which checks for dependencies, builds, optimizes, and verifies WASM binaries, replacing ad-hoc shell commands in the CI workflow. [1] [2]

• Updated the Rust toolchain to version 1.86.0 and specified required components and targets for consistent development and CI environments. [1] [2]

Contract and Codebase Updates:

• Added a Migrate {} variant to the MigrateMsg enum in the converter contract for future-proofing migrations.

CI and Dependency Updates:

• Updated the version of cargo-tarpaulin used for code coverage in CI to 1.90.0 for improved compatibility and reliability.
