…vation on Blake2 flag Add get_contract_address_blake (optimized Blake2s via hash_state_blake) and a get_contract_address_with_hash wrapper, and gate both deploy syscalls on a new use_blake_address_derivation flag, plumbed from OsHintsConfig through a hint into BlockContext. The flag defaults to false (Pedersen), so this is behavior-preserving. Regenerates os_resources, constants.cairo, the program hash, and hint-coverage snapshots for the runtime-charged +15-step deploy overhead, and adds a Cairo<->Rust parity test for the Blake2 derivation.
