vmactions/freebsd-vm uses QEMU to run FreeBSD in a VM, which requires a
standard GitHub-hosted runner with KVM support. The self-hosted-ghr
runner was failing with SSH exit code 255 because the VM couldn't boot.
Changes:
- Use ubuntu-latest instead of self-hosted-ghr
- Move pkg install to prepare: (runs before code sync)
- Add usesh: true for consistent shell behavior
- Print go version for debugging
