Crate wasmsh_vm 

Cooperative virtual machine for the wasmsh executor subset.

The full shell still runs primarily in wasmsh-runtime. This VM is used for the lowered IR subset and provides the shared budgeting, cancellation, diagnostics, and output accounting primitives that the runtime also relies on for resumable execution.
