v3.1.6

# Changelog

## New Features:

- **Eval Case Run Arguments**: `Case` takes `session_id`, `user_id`, `session_state`, `dependencies`, `metadata` and `knowledge_filters`, forwarded to the agent or team run, and `input` accepts a `Message`, so a case can attach an image or file to the graded turn. Cases sharing a `session_id` run as consecutive turns. See [cookbook](https://github.com/agno-agi/agno/blob/main/cookbook/09_evals/suite/suite_session.py).

## Improvements:

- **OS Manager Docs Access**: OS Manager queries the Agno documentation directly for framework questions instead of delegating to Platform Manager, and keeps delegated tasks scoped to the question. `access_docs` now covers both.
 - **Result Offloading Search and Readback**: `search_result` returns separate passages from one long line, such as single-line JSON, instead of only the first match, and `read_result` takes `max_chars` to read a smaller excerpt.
 
## Bug Fixes:

- **ParallelTools**: Copying an agent or team with `ParallelTools`, as AgentOS does on every request, keeps the live SDK client and gives the copy its own settings, without `RLock` copy errors or `_state` finalizer warnings.
