Split the rootless Tor e2e skip so the deterministic offline checks (the
real offline onion keygen and the production-flag guard) run whenever the
tor binary is present, while only the live onion round-trip stays gated on
LIM_E2E_TOR=1. The pytest job now installs tor so the keygen — which
validates the exact production keygen path — runs on every push. A separate
continue-on-error tor-network-e2e job exercises the full round-trip without
making the public Tor network a blocking merge gate.
The full QEMU build/boot/unlock e2e still needs root + KVM + Arch tooling
and stays local/opt-in.
