hal speaks pver 5: preimages prove their size, and fees round up as one

0.6.0 servers require the new hashlock clauses (OP_SIZE 32 guard) for
Lightning and rounds. New policies/transitions carry the v1 scripts and
type bytes; _v0 variants keep old vtxos reconstructing and exiting.
The retired third-party HTLC policy is dropped (upstream took 0x08).
