Go SDK

The SDK ecosystem expanded with new experimental tooling while the core and AI modules refined their infrastructure. The team shipped ldmiddleware as a new experimental library providing utilities for scoped clients and automatic context/event handling, bumped the minimum Go version to 1.24 across ldotel and ldmiddleware, and added AI Config judge support to the ldai module. Meanwhile, the main SDK improved its data system configuration to accept lists of synchronizers and enhanced fallback behavior for custom configurations.
