feat(dask): remove dask

[paul-nechifor]

Problem

• Dask is slow to start.
• Causes issues with shutdown (you get ugly errors when hitting Ctrl+C).
• Required a lot of ugly patches in core/__init__.py
• Causes confusion because things are imported once per worker. (E.g.: see Jeff's rerun issue, or my actor confusion)

Closes DIM-609

Solution

• Removed the dask package entirely.
• Moved imports out of dimos.core. Now you have to import from the original place.
• Removed everything in dimos/core/__init__.py.
• Made dimos shut down cleanly, without any exceptions, and right away.

Breaking Changes

• UtilizationModule is gone.
• Blueprint configurations cannot use lambdas anymore because multiprocessing requires params to be pickleable, and lambdas are not because they don't have names. This worked with Dask because Dask serialized the bytecode of the lambda and reconstructed it on the other side.

How to Test

Test any blueprint. Example:

uv run dimos run unitree-go2

Too many files changed for review. (133 files found, 100 file limit)

[paul-nechifor]

The reason this change is needed is because multiprocessing can't pickle lambdas. Lambdas don't have names so they can't be pickled because there's nothing to reference them from the other side.

Dask cheats by serializing the bytecode of the lambda.
