Create GitHub Actions Release Workflow for Optimized WASM

[Code-Paragon]

Problem

The project provides a make optimize command, but there is no automated process to securely build and attach the minimized .wasm binary to GitHub Releases.

Expected behavior

A GitHub Actions workflow is created that triggers on tag creation, compiles the contracts, runs soroban contract optimize, and uploads the final .wasm file as a release artifact.

Files to update

• .github/workflows/release.yml (create)

Project relevance

Ensures that institutions and frontend deployments always have access to a deterministic, securely compiled, and size-optimized binary straight from the source repository.

Acceptance criteria

• Feature works as described
• Tests are added or updated where needed
• Documentation is updated where needed
• The workflow utilizes the soroban-cli to perform the optimization step before upload
• No TypeScript, lint, test, or build errors
