Extend the differential property tests (sigp#47) and derive macro tests (sigp#48) to cover the new functionality in the progressive branch: - Property test ProgressiveMerkleHasher against a recursive reference implementation of EIP-7916 merkleize_progressive, with random byte lengths and random write splits to exercise the partial-chunk carry buffer, up to 128 chunks to cross all early level boundaries. - Property test ProgressiveBitList hashing against the same reference with independent bit packing, covering the empty-list workaround. - Derive tests for progressive containers: skip_hashing interaction, nesting (both directions), generics, tree_hash_type, a six-field container crossing a progressive level boundary, and active_fields spanning multiple bytes. - Hard-coded roots for the level-crossing and multi-byte cases computed independently from the EIP pseudocode, so these tests do not rely on the hasher under test.
