Add GitHub Actions CI workflow with vitest setup

- Create test.yml workflow that triggers on PR to main
- Install Rust & Node.js in CI steps
- Add vitest configuration for frontend and backend
- Add test scripts using 'npm test' (vitest run)
- Add linting steps for code style consistency
- Configure cargo test for contracts
- Add sample tests to verify setup
- Fail workflow if any tests fail

Acceptance Criteria:
✓ Workflow triggers on PR to main
✓ Steps to install Rust & Node
✓ Fails if tests fail

Additional Features:
✓ Linting steps for consistent code style
✓ Named 'CI / Validation' for clarity
✓ Uses vitest run via npm test
✓ Caches dependencies for faster runs
