Add a --headless flag to the Host.app Run subcommand for running
macOS VMs without a GUI, enabling use from test frameworks.
Key changes:
- HostCli.swift: When --headless is set, run the VM via VMController
+ RunLoop.main.run() instead of NSApplicationMain. Using the
RunLoop (not dispatchMain) is required because VZ framework
callbacks depend on RunLoop sources.
- VMController.swift: Add headless parameter to createVirtualMachine
that configures a single socket-based NIC (no NAT NIC). This
matches the NIC configuration used when creating/saving VMs, so
saved state restoration works correctly. A NIC count mismatch
causes VZ to silently fail to execute guest code.
- TailMacConfigHelper.swift: Clean up socket network device logging.
- Config.swift: Move VM storage from ~/VM.bundle to
~/.cache/tailscale/vmtest/macos/.
- TailMac.swift: Fix dispatchMain→RunLoop.main.run() in the create
command (same VZ RunLoop requirement).
