Feature/ci workflow

[4wardAerial]

Description

Adds a GitHub Actions workflow for continuous integration, running automatically on pushes and pull requests targeting main and develop. The pipeline performs repository checkout, Node.js environment setup, dependency installation, linting, and test execution with coverage reporting.

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update

Changes Made

• Added .github/workflows/ci.yml defining the CI job;
• Configured triggers for push and pull_request events on main and develop branches;
• Added steps: actions/checkout@v4, actions/setup-node@v4, npm ci, npm run lint, and npm run test -- --coverage;
• Added coverage/ to .gitignore, since it is a regenerable build artifact and should not be versioned.

How to Test

1. Confirm the CI workflow appears running under this PR's checks (or in the Actions tab) after each push;
2. Temporarily introduce a lint violation (e.g. an unused variable) in any .ts file, commit and push to confirm the Lint step fails with the corresponding ESLint error in the log;
3. Revert the lint violation, then temporarily add a failing test (e.g. expect(1).toBe(2)), commit and push to confirm the Coverage tests step fails with the corresponding Jest assertion error;
4. Revert the failing test and confirm all steps pass;
5. Confirm the job is available for selection under Settings → Branches → Require status checks once it has run at least once.
