Code Review

This pull request introduces a KSP processor for generating Firebase AI schemas, which is a fantastic addition for improving developer experience with Firebase AI. The implementation is well-structured. I've provided a few suggestions to address some minor bugs in the processor logic, improve the API design of the published artifact, and fix some minor formatting issues. Overall, great work!
