LiteAgents 0.3.0a6: portable tools and simpler setup

LiteAgents keeps one application setup while you change the harness. This preview adds simpler tools and scoped native controls, and updates every cookbook to use the same direct-provider setup.

• Pass typed Python functions as tools; LiteAgents generates their schemas and adapts them to each harness.
• Use LiteAgentClient(profile=profile, tools=[lookup_order]) and query(prompt=..., profile=profile) directly. Existing LiteAgentOptions and Tool classes remain supported.
• Declare subagents without a separate enable flag.
• Put optional native controls under each harness's name in harness_options; switching and fallback select the matching settings automatically.
• Follow short Colab walkthroughs for tools, MCP, conversations, approvals, retries, fallback, profiles and Temporal recovery. Provider keys work directly through the LiteLLM SDK; a gateway is optional.

Install the preview with the harnesses you want:

python -m pip install "liteagents[pydantic-ai,claude-sdk] @ https://github.com/BerriAI/liteagents/releases/download/v0.3.0a6/liteagents-0.3.0a6-py3-none-any.whl"

Validation exercises the same function-and-MCP application across all six harness selectors in direct and Temporal execution, with real native loops and controlled model responses. Fresh-wheel checks include notebook reruns and a separate Temporal worker crash/restart. These are not live-provider acceptance tests.

For durable deployments, upgrade clients and workers together and use a new profile version for new jobs. Finish existing jobs on their original SDK/profile versions. Interrupted external writes still require application idempotency.
