zeekay a93f6e3dec build the VMs without the daemon in their closure
A plugin is its own binary; the daemon that loads it has no business being
linked into it. Twelve VMs reached into github.com/luxfi/node for four things,
and each one now programs against a home that is actually its own:

- fee admission (Policy, FlatPolicy, NoUserTxPolicy, Validate) joins the
  settlement half already in chains/fee. One fee package, and the nodefee alias
  that marked the split is gone.
- the cross-chain artifact types move to chains/artifacts.
- the factory the daemon registers is luxfi/vm/manager.Factory, and the version
  types are luxfi/version. Both are ordinary modules the daemon reads too, so a
  VM imports them directly rather than through anything of ours.

The GPU switch is deleted, not moved. It was a global set during daemon startup
that a separate process could never observe, so every plugin read its default;
FHEOptions.Backend is the switch that was really there.

go list -deps names no luxfi/node for aivm, bridgevm, dexvm, evm, fhevm,
graphvm, identityvm, keyvm, mpcvm, quantumvm, schain or zkvm, and the built
plugin binaries carry no such string. oraclevm and relayvm still do: they are
re-export shims over luxfi/oracle and luxfi/relay, which build their fee
policies upstream. Their tests keep naming the daemon's fee package because
that is the type their value has.
