[FEATURE] Integrate Kernel-Level Sockmap Splicing and Zero-Allocation Vectorized Serializers

Problem

Envoy's go-control-plane pushes standard xDS updates to user-space proxy routing arrays [1.5]. However, processing heavy multi-tenant context bit arrays over traditional userspace networking sockets triggers massive heap allocation overhead, causing random thread scheduling garbage collection latencies and token re-computation failures [1.5, 1.6].

Proposed Solution

Introduce ultra-low-overhead kernel abstraction boundary handlers inside internal/control/:

1. /api/v1/kernel/splice: Direct sockmap stream handler that executes zero-copy packet redirection inside the Linux kernel under <2ms [1.5, 1.6].
2. /api/v1/vector/serialize: Zero-allocation binary snapshot serializer leveraging SIMD hardware execution registers instructions to completely eliminate userspace memory ceilings overhead [1.5].

Alternatives

Standard protocol buffering or JSON string encoding configurations, which were completely rejected due to heavy serialization tail latency spikes.

Use Case

Secures 100% data-plane autonomy and maintains infinite infrastructure resilience across global multi-region application deployment grids, protecting processing margins natively [1.5, 1.6].

Start by reviewing the existing repository structure and the internal/control/ area; the issue does not identify current entry points, tests, or implementation constraints. Clarify how the proposed /api/v1/kernel/splice and /api/v1/vector/serialize handlers should integrate with xDS updates, then define tests that demonstrate kernel redirection below 2ms and zero-allocation serialization before implementation.
