Introduces a builder pattern for configuring MariaDBVectorStore instances and
improves the overall implementation. This change:
- Makes configuration more flexible and type-safe through builder methods
- Deprecates old constructors and builder in favor of the new builder pattern
- Adds comprehensive validation of configuration options
- Improves documentation with clear examples and better structure
- Updates all test classes to use the new builder pattern
- Adds comprehensive builder tests
- Updated reference documentation
The builder pattern provides a more maintainable and user-friendly way to
configure vector stores while ensuring configuration validity at compile time.
This aligns with the project's move towards using builder patterns across all
vector store implementations.
