Create Tasksets

Goal

Create native v1 tasksets that are installable and runnable with verifiers.

To start, ALWAYS use the CLI to create a package with the correct files:

uv run vf-init my-task-v1

Add only the components the contract needs:

uv run vf-init my-task-v1 -T      # task toolset
uv run vf-init my-agent-v1 -H     # custom reusable harness
