Update required: Knowledge search API endpoint renamed

We renamed the knowledge search endpoint from search_vectors to search_knowledge. This is a breaking change and aligns the API with terminology used across the platform. Clients calling the old route will fail until updated.

Details

• Breaking change: update integrations to call search_knowledge
• No change to request/response payloads; only the route name is updated
• Improves clarity and consistency across Knowledge capabilities

Who this is for: Teams integrating knowledge retrieval in agents, workflows, or custom services.
