…shold keys to CMP, and security-model documentation Squashed sync of internal development since the previous public update. Integrator-visible changes - platform_service gains a pure virtual fill_frost_signing_info_from_metadata(); existing subclasses must implement it. - cosigner_sign_algorithm gains SCHNORR_SECP256K1, SCHNORR_SECP256R1 and SCHNORR_STARK, appended so existing values are unchanged. - bam_signature_metadata_header now derives from a shared two_party_signature_metadata_header, and the BAM generated_public_key / add_user_data types are now aliases of shared types in types.h. - bam_ecdsa_cosigner::decrypt_and_rebuild_private_share was removed in favour of the shared utility function.
