/**
 * Cognitive Kernel Plugin
 *
 * Cognitive augmentation for LLM reasoning with working memory,
 * attention control, meta-cognition, scaffolding, and cognitive load management.
 *
 * Features:
 * - Working memory slot management (Miller's 7 +/- 2)
 * - Attention control (focus, diffuse, selective, divided, sustained)
 * - Meta-cognitive monitoring and reflection
 * - Cognitive scaffolding (decomposition, analogy, Socratic, etc.)
 * - Cognitive load theory optimization
 * - SONA integration for continuous learning
