add parsl to agents

[miketynes]

Right now the agents perform computation themselves. We want to achieve concurrency through parsl.

The SC25 MOFA example is an OK starting point (https://github.com/academy-agents/sc25-agentic-mof-workflow/tree/main/mofa/agentic) but we also want to do things a little more explicitly and avoid the parsl decorators if we can. We can use a ParslPoolExecutor for this: https://parsl.readthedocs.io/en/stable/stubs/parsl.concurrent.ParslPoolExecutor.html#parsl.concurrent.ParslPoolExecutor
give each agent one of these and then handle work by pulling from the agent's queue, and use wrap_future for compatibility
