feat(vm): add openshell-vm crate with libkrun microVM gateway#611
Conversation
Fix targeted gvproxy kill to use tracked PID from runtime state instead of pkill, gate diagnostic dump behind OPENSHELL_VM_DIAG env var, stream SHA-256 hashing to avoid buffering entire files, clarify operator precedence in env var validation, replace hand-rolled JSON parser with serde_json, deduplicate required_runtime_lib_name(), and add openshell-vm to AGENTS.md architecture table.

Summary
Adds the
openshell-vmcrate — a new microVM runtime that uses libkrun to boot lightweight VMs with hardware isolation. On macOS ARM64 it leverages Apple's Hypervisor.framework; on Linux it uses KVM. This provides a single-binary alternative to the Docker/k3s-based gateway deployment.Changes
