CHT Configuration Test Harness

The `cht-conf-test-harness` is a JavaScript/TypeScript test framework designed specifically for validating configurations of applications built on the Community Health Toolkit (CHT) Core Framework. It simulates a CHT application instance, allowing developers to write and run automated tests against their app configurations without deploying to a live environment. The current stable version is 5.0.4, with frequent minor releases addressing bug fixes and major versions typically aligning with significant updates to the CHT Core Framework. A key differentiator is its explicit compatibility matrix, ensuring tests can target and validate against specific CHT Core versions (e.g., v5.x supports CHT Core 4.11.x+). It is commonly used with testing frameworks like Mocha and assertion libraries like Chai.
