Covers deepEqual, polyfillRequestAnimationFrame, validateConfigId, the default client singleton, and an end-to-end expansion of the initialize() client tests (URL parsing, config/elements/style APIs, event handlers, promise resolution and rejection, unsubscribers, and destroy behavior). React-dependent modules are intentionally left untested since react is only an optional peer dep and is not installed in the test environment.

This PR significantly expands the test suite for the plugin client, replacing minimal lifecycle tests with comprehensive coverage of all client APIs and functionality.
Summary
The test suite for
initialize()has been completely rewritten to provide thorough coverage of the plugin client's behavior, including lifecycle management, configuration API, elements API, style API, and message handling. Additionally, new test files have been added for utility functions and the client singleton export.Notable Implementation Details
