Simplify integrations with synchronous Knowledge operations

Knowledge add_content_ methods now support true synchronous execution. This removes the async-only limitation, making it straightforward to integrate content ingestion into synchronous services and batch jobs without event loop management or architectural workarounds.

Details

Synchronous parity with existing async methods for consistent behavior
Drop-in for frameworks and environments that don’t use async
No migration steps required

Who this is for: Backend teams building on synchronous frameworks and data pipelines that need reliable, easy-to-use Knowledge ingestion.
