chore: add use client banner to build configuration

[healtheloper]

Description

This PR adds a 'use client' banner to the build configuration, ensuring the directive is included at the top of all bundled output files. To ensure compatibility with React Server Components (RSC) environments, such as the Next.js App Router.

Changes

Added banner option in tsup configuration.

Motivation and Context

An error occurred during the build.

How Has This Been Tested?

Inspected the build output files (in the dist folder) to verify that the 'use client'; banner was correctly added to the top of each file.

Installed the locally built library into the test project.

Screenshots (if appropriate):
