Agno 3.0.0 splits agent runs out of the session row

Agno released version 3.0.0 with a breaking migration that pulls agent runs out of the shared session row, per Agno's 3.0.0 release notes.

Long-running agents on DynamoDB or Firestore have been hitting those databases' hard per-item size limit.

Every run used to get packed as JSON into the session row, so write cost scaled with the square of the message count. The new agno_runs table gives each run its own columns instead of one shared blob. Write cost now scales linearly, and the size ceiling is gone.

The release also adds offload_tool_results=True for context pressure inside a single run. Any tool result over 16,000 characters gets written to AgentFS. The model gets read_result and search_result calls to pull it back in pieces, so the full payload never sits in context.

CodeMode goes further than a schema of separate tools. It gives the model one IPython kernel that persists for the whole session, and tools become Python handles the model calls directly in code.
