ci: release flow

[fmorency]

This pull request introduces a new GitHub Actions workflow for automating the build and release process of WebAssembly (WASM) artifacts. The workflow handles building, optimizing, and publishing WASM binaries and their checksums when a release tag is pushed or manually triggered.

Release workflow automation:

• Added .github/workflows/release.yml to automate building, optimizing, and releasing WASM artifacts, including generating checksums and uploading assets to GitHub Releases.
• Configured the workflow to trigger on pushes to tags matching v* and via manual dispatch with a specified tag.
• Set up Rust toolchain and WASM target, installed necessary dependencies (protobuf-compiler and wasm-opt), and optimized WASM binaries using wasm-opt.
• Automatically generates SHA256 checksums for the released WASM files and includes them in the release.
• Uses softprops/action-gh-release to create a GitHub release and upload the WASM artifacts and checksums.
