Swiss AI Hub v0.291.6

Changed

• 🚀 Enhanced LLM Guard Performance: Switched agent description and few-shot guards to use asynchronous structured
  prediction, improving responsiveness and concurrency with Large Language Models.
• ⚡️ Improved Concurrency for Reranking Nodes: Blocking reranking operations are now offloaded to a separate thread
  using asyncio.to_thread, preventing event loop starvation and boosting application performance.
• 📄 Refined Error Logging: Updated MineruLoader and Redis request hooks to use logger.exception, ensuring
  comprehensive exception details are automatically included in logs for better debugging.
• 🛠️ Corrected OpenTelemetry HTTPX Instrumentation: Ensured asynchronous HTTPX request and response hooks are
  properly defined as coroutine functions, enabling full observability for async HTTP communications.

Refactor

• 🧹 Optimized Dispatcher Event Handling: The _build_event_kwargs method in agent and process dispatchers, as well
  as the base dispatcher, has been made synchronous, streamlining event argument construction.
• 🔄 Standardized Access Rule Prefixes: Consolidated aihub.admin and aihub.user access rule prefixes into
  dedicated constants, enhancing maintainability and clarity across authentication logic.
• 🔑 Centralized Authentication Error Messages: Moved common error messages in the authentication handler to
  constants, improving consistency and simplifying future updates.
• ☁️ Standardized S3 Service Error Messages: Consolidated error messages for S3 anonymous file access service
  operations into constants, improving consistency and maintainability.
• ⚙️ Refined SonarQube Configuration: Added specific ignore rules to sonar-project.properties to suppress
  python:S1192 (duplicated string literals) warnings for known-good patterns, such as lazy imports and MongoDB query
  syntax, reducing false positives in code quality scans.
• 📝 Improved RPC Success Attribute Handling: Standardized the rpc.success attribute for NATS requester tracing
  using a dedicated constant.
• 📚 Improved Test Mock Clarity: Added noqa comments to asynchronous mock methods in authentication utilities and
  Milvus vector store tests to explicitly state why they remain async for testing purposes, improving code clarity for
  linters.
• 🧹 Minor Python Idiom Improvements: Updated set creation from set(generator_expression) to {comprehension} in
  base_event and dispatchable_workflow for more idiomatic Python.
