Adjust README copy and root route test

Minor README copy edit ('Production-ready' -> 'Production ready' and removed trailing period) and update tests to match the API response. The root endpoint test docstring was updated to reflect that the endpoint returns API metadata, and the assertion for a top-level 'data' key was removed so the test now only checks for 'meta' and 'meta.title'. This aligns tests with the current response structure.
