Delegation - allow delegator to spawn sub-agent from a pool of pre-configured agents

[simonrosenberg]

The delegator should be able to spawn agents from a pool of pre-defined sub-agents.

Those sub-agents should be entirely customizable

1. specific tools
2. specific skills
3. specific system prompt

Code validation
In the example software-agent-sdk/examples/01_standalone_sdk/25_agent_delegation.py, specific sub-agents should be defined in a simple way and be made available for the delegator to spawn using their name.

The example software-agent-sdk/examples/01_standalone_sdk/25_agent_delegation.py should run end-to-end with specific sub-agents.

I believe #1223 addresses this at least in part. @simonrosenberg Is there anything left to do on this or should we close?

I forgot to close that issue, thanks for reminding me!
