 * ║  AGENT-FIRST RUNTIME — DETERMINISTIC EXECUTION AUTHORITY                 ║
 * ║                                                                          ║
 * ║  This module provides a high-level runtime API designed for AI agents    ║
 * ║  (Replit, Lovable, Claude Code) to reliably execute deterministic code.  ║
 * ║                                                                          ║
 * ║  Key Features:                                                           ║
 * ║  - Deterministic PRNG: runtime.random() (seeded Mulberry32)              ║
 * ║  - Deterministic noise: runtime.noise(x, y?, z?) (seeded Perlin)         ║
 * ║  - Strict mode: Throws on Math.random, Date.now, performance.now         ║
 * ║  - Digest: Stable hash for verification and replay                       ║
 * ║  - State snapshot: Canonical state for bundles                           ║
 * ║                                                                          ║
 * ║  BROWSER-SAFE: No Node.js dependencies. Works in Vite/Next/React.        ║
