SCSS good first issues

AI Summary: This issue proposes replacing the unreliable, mocha-based build test with a deterministic smoke test in the release preparation workflow. The new test will verify the presence of the correct version string in CSS files and ensure the compiled CSS is not empty, preventing releases with faulty builds.

AI Summary: This issue proposes replacing deprecated `MediaQueryList.addListener()` and `.removeListener()` methods with the standard `addEventListener()` and `removeEventListener()` in the `usa-footer` package. This change is necessary because the older methods are deprecated and `MediaQueryList` now inherits from `EventTarget`, making the standard methods universally supported in the project's target browsers.

AI Summary: This issue proposes adding the "type": "module" field to the root package.json to standardize JavaScript module handling within the repository. This change is internal and won't affect consumers, but requires updating Vite configuration files to correctly handle the new module type and removing redundant per-directory package.json files.

AI Summary: This issue proposes renaming several Node.js CommonJS tooling files to use the `.cjs` extension. The goal is to explicitly declare their module format by filename, rather than relying on the absence of a `"type": "module"` field in `package.json`. This is an optional, purely cosmetic change that does not affect functionality and can be done at any time.

Developers must adhere to specific conversion rules and ensure prerequisite issues are merged and released before starting.

AI Summary: This issue is part of a larger migration to convert the USWDS JavaScript components from CommonJS to ESM. Specifically, it requires converting the source code and tests for `usa-range`, `usa-tooltip`, and `usa-validation` to use ESM syntax. Developers must adhere to specific conversion rules and ensure a prerequisite issue is merged and released before starting.

AI Summary: This issue is part of a larger migration to convert USWDS JavaScript components from CommonJS to ESM. Specifically, it requires converting the `usa-input-mask` and `usa-language-selector` components and their tests. Developers must ensure a prerequisite issue related to package exports is merged and released before starting, and follow specific conversion rules for imports.

AI Summary: This issue involves converting three specific JavaScript components (usa-password, usa-file-input, and usa-in-page-navigation) from CommonJS to ESM. This is part of a larger migration effort to modernize the codebase. Developers must adhere to specific conversion rules and ensure a prerequisite issue is merged before starting.

AI Summary: This issue is part of a larger migration to convert the USWDS JavaScript components from CommonJS to ESM. Specifically, it requires converting the `usa-header` component's source and tests, as well as the spec files for `usa-nav`. Developers must wait for another specific issue (#6852) to be merged and released before starting this task.

AI Summary: This issue is part of a larger migration to convert JavaScript components from CommonJS to ESM. Specifically, it requires converting the `usa-combo-box` and `usa-modal` components and their tests to ESM. This needs to be done in a single pull request to avoid breaking the build process due to interdependencies between these two components.

AI Summary: This issue involves converting the `usa-date-picker` JavaScript component from CommonJS to ESM. It's part of a larger migration effort and requires specific steps to ensure compatibility with existing consumers, including adding named re-exports for certain functions. The conversion should only begin after a related package export issue has been merged and released.

AI Summary: This issue involves converting the `usa-time-picker` JavaScript component from CommonJS to ESM. It's part of a larger migration effort and has specific prerequisites regarding package exports and dependencies that must be addressed first. The conversion follows strict rules for handling imports and destructuring.

AI Summary: This issue involves converting the `usa-date-range-picker` JavaScript component from CommonJS to ESM. It's part of a larger migration effort and has specific prerequisites regarding package exports and conversion order. The conversion follows strict rules for handling default imports and destructuring.

AI Summary: This issue involves converting two JavaScript files, `start.js` and `index.js`, from CommonJS to ECMAScript Modules (ESM) as part of a larger migration effort. The conversion is designed to be the safest first step, ensuring that downstream components are ESM-tolerant before they are modified. Specific conversion rules are provided for handling default imports and destructuring.

AI Summary: This issue requires updating the `package.json` `exports` field to point to built CommonJS artifacts instead of raw source files. This is a crucial first step in migrating from CommonJS to ESM, ensuring that future source code changes do not break existing consumer code.

AI Summary: This issue proposes adding a new Rollup build step to generate individual CommonJS files for each USWDS component and a component barrel. This is a preparatory step to address future changes in package exports, ensuring a smooth transition for CommonJS consumers without immediate user-facing impact.

AI Summary: This issue proposes replacing Browserify with Rollup as the JavaScript bundler for USWDS. The primary goal is to prepare the build process for future migration to ES Modules, as Browserify cannot currently handle ESM syntax. The source code will remain CommonJS for this change, and Babel and Uglify will be retained.

AI Summary: This issue aims to improve ESLint configuration to better detect mistakes when converting between CommonJS and ES Modules (ESM) in the USWDS project. It proposes restructuring the ESLint configuration to apply specific rules to ESM files, such as catching incorrect named imports from CommonJS modules and preventing import cycles.

AI Summary: This issue proposes adding an automated test to verify the `package.json`'s `exports` map in the USWDS JavaScript package. The test will simulate how consumers import modules to ensure the exported paths resolve correctly, acting as a safety net for future changes that repoint exports from source to built artifacts.
