FEAT: Integrate Crystal Logic & VL-JEPA Architecture

[github-actions]

Description

This feature integrates the "Crystal Logic" architecture from Jules (PR #383) and adapts key logic from the VL-JEPA paper (https://arxiv.org/html/2512.10942v1), specifically "Selective Decoding" and "Predictive Embedding".

Context

• PR Implement Crystal Logic Architecture #383: Introduces HoloPacket, RefractionIndex, and PolarizationSignature.
• VL-JEPA: Proposes efficient video/stream processing via embedding prediction stability.

Goals

1. Merge Crystal Logic: Incorporate the foundational structures from PR Implement Crystal Logic Architecture #383.
2. Adapt Selective Decoding: Implement logic to skip decoding/processing when semantic variance in the polarization signature is low.
3. Predictive Embeddings: Enhance the HoloPacket flow to support predictive states (Prediction vs Target).

Tasks

• Merge PR Implement Crystal Logic Architecture #383
• Refactor HologramCodec to support variance-based selective decoding.
• Add tests for semantic stability transmission.
