…ative capabilities - Added optional generative provider parameter to various methods in TypedGenerateClient for enriching prompts. - Introduced after cursor for pagination in FetchObjects methods across TypedGenerateClient and TypedQueryClient. - Implemented hybrid search methods in TypedQueryClient to support keyword and vector searches with grouping. - Enhanced NearVector methods in TypedQueryClient to utilize lambda functions for vector building. - Updated documentation to reflect new parameters and functionalities.
…, and enhance documentation - Consolidated NearText API overloads across QueryClient, GenerateClient, AggregateClient, and Typed clients. - Introduced convenience overloads for text-only Hybrid search and NearText target vectors. - Updated method signatures to accept TargetVectors directly instead of using FactoryFn. - Enhanced documentation for NearText methods, including examples for new usage patterns. - Added extension methods for NearText search with lambda target vector builders in Typed clients. - Updated tests to validate new NearText functionality with multiple target vectors.
- Introduced new methods for searching near vectors using NearVectorInput records in TypedGenerateClient. - Added overloads for NearVector methods to support lambda builders for NearVectorInput. - Updated TypedQueryClient to handle HybridVectorInput and improve hybrid search functionality. - Refactored NearText methods to utilize NearTextInput records and support lambda builders. - Improved documentation for new and existing methods to clarify usage and parameters.

Overview
This PR significantly enhances the vector search API by introducing flexible syntax patterns, comprehensive builder interfaces, and improved type safety for multi-target vector operations.
Key Improvements
1. Flexible Vector Input Syntax 🎯
Introduced multiple ways to specify vectors in searches, supporting various coding styles:
2. Multi-Target Vector Combinations 🔄
Added support for multiple combination strategies:
3. Hybrid Search Enhancements 🔀
Simplified hybrid search with flexible input options:
4. Improved Type Safety ✨
float[]toVectortypefloat[],double[],int[], etc.)5. Comprehensive Test Coverage 🧪
Added 126 new unit tests covering all syntax patterns:
All tests validate request structure and ensure API consistency.
6. Enhanced Mock Infrastructure 🔧
