Adds a mechanism to pin protocol contract artifacts via pinned-protocol-contracts.tar.gz, mirroring the existing pinned-build support in noir-protocol-circuits. When the tarball is present, the build extracts pre-compiled protocol contract artifacts and skips their compilation. This prevents changes to aztec-nr from altering the protocol contracts hash, which must remain stable for mainnet compatibility. Usage: ./bootstrap.sh pin-protocol-contracts This builds only the protocol contracts and creates the tarball. Commit pinned-protocol-contracts.tar.gz to freeze the artifacts.

Problem: The
mainnet_compatibility.test.tstest checks thatprotocolContractsHashmatches a hardcoded mainnet value. We missed protocol contracts while pinning protocol circuits.Solution:
