Assert error after enabling cypress

[jojozhuang]

After enabling cypress(see PR #65):

• npm run build is ok
• npm run test:headless is ok
• npm run e2e:headless is ok.

However, npm run lint has errors. Have to add the following rules into eslint.config.mjs to ignore the errors.

        "@typescript-eslint/no-unsafe-call": "off",
        "@typescript-eslint/no-unsafe-member-access": "off",

In addition, I see `Property 'toBeTruthy' does not exist on type 'Assertion' error in VSCode.

The issue is that Cypress types are overriding Jasmine types because Cypress also has its own expect assertions.
