v1.14.0-prerelease.1

What's New

All tools now return structured response data alongside their text output, making it easier for AI assistants to reliably parse and use results without additional reformatting — this also improves resistance to prompt injection. A bug affecting local Atlas deployment creation has been fixed, where the tool would sometimes return before the deployment was fully ready, causing connection failures.
