/**
 * Optimization Pack (pack.json v1) — the shareable envelope.
 *
 * See docs/optimization-packs.md. A pack bundles data-type parts (prompts,
 * skills, memory) and code-type parts (components, workflows) described by a
 * single pack.json, with a content-addressed integrity digest so a pack cannot
 * be silently modified in transit.
 *
 * This module parses/validates pack.json and computes/verifies integrity. It is
 * pure (no bundle mutation); import wiring lives elsewhere.
