Zig-Based Attestation Client

Description

Cryptographic attestation layer implemented in Zig that sits below the Claude Code JS layer and proves the API request comes from a genuine Claude Code binary. Previously hinted at by the leak; v2.1.113's native-binary spawn now exposes this layer to ordinary CLI users. Complements Bun-Level Zig HMAC Request Signing.
