* refactor(crypto): deprecate custom sha256 in favor of OpenSSL libcrypto - Remove standalone src/foundation/sha256.cc, include/mocktail/sha256.h, and tests/sha256_test.cc - Remove mocktail_crypto_foundation library and sha256_test targets from CMake - Export clean FileDigest and HashText helpers via include/update/payload_integrity.h - Deduplicate byte-to-hex formatting across host ABI loader and updater modules - Support direct generation hash sizing to avoid repetitive string slicing - Validate all EVP return codes across streaming downloads and asset tree hashing * fix(compat): abort candidate canary registration when profile hashing fails - Return Failure before profile validation and registration if ComputeSha256Hex fails - Propagate canary attestation hashing failures in ValidateCanaryAttestation - Add SetHostAbiProfileHashingFaultForTesting hook and regression test in host_abi_profile_test --------- Co-authored-by: glook9001 <310372091+glook9001@users.noreply.github.com>
