v14.12.0

Fixed issue where __name__ fields with DESCENDING order were incorrectly filtered from index listings, causing duplicate index issues (#7629) and deployment conflicts (#8859). The fix now preserves __name__ fields with explicit DESCENDING order while filtering out implicit ASCENDING __name__ fields.
Fixed an issue where firebase init dataconnect didn't enable the Data Connect API by default (#8927).
Add firebase init aitools to help developers set up Firebase AI tools in their projects (#8949).
Updated the Firebase Data Connect local toolkit to v2.11.0, which includes the following changes (#8948):
- [Fixed] Kotlin code generation with enums
- [Fixed] Deploying schemas with enums would report false breaking changes
- [Added] Support for ordering results by aggregate fields (min/max/count/sum/avg).
- [Added] Support for built-in and user-defined enums to LLM Tools generation.
