Fix #149: Configured code coverage

[tarunsinghofficial]

Fixes #149

Changes Made:

• Configured Vitest for code coverage in existing vite.config.js
• Added a new script npm run test:coverage to generate test coverage reports locally.
• Added coverage/ folder to .gitignore to prevent committing generated reports.

Screenshot of Coverage folder:

After running the test suite using npm run test:coverage, we can generate the coverage report in the coverage folder.

thanks for tackling this! It looks like the test.coverage.exclude array needs to be expanded a bit. In the coverage I see wayfinder/build, wayfinder/.svelte-kit and wayfinder/node_modules, all of which should be excluded.

Sure, will exclude all of these.
