Add the initial diagnostics renderer for verifier reports and wire it into the BPF build. The helper emits the common failure header through the verifier log. Later patches add prose wrapping, reusable report sections, and source and instruction context for category-specific diagnostics. Gate the helpers on normal verifier log output from the start, so BPF_LOG_STATS-only loads do not collect or render diagnostics.
