/**
 * Validates pipeline state before executing a phase, returning user-friendly
 * error message if prerequisites are missing or outdated.
 *
 * Enforces the waterfall dependency structure: each phase requires all previous
 * phases to be completed with matching step counters. When requirements change
 * (analyze step increments), downstream phases become invalid through step
 * mismatch, and this function generates clear messages guiding users to
 * regenerate affected phases.
 *
 * This is the gatekeeper preventing users from executing phases out of order or
 * with stale dependencies, ensuring generated artifacts always reflect current
 * requirements. Without this validation, users could generate API
 * implementations based on outdated database schemas, causing subtle bugs.
 *
 * @param state Current pipeline state
 * @param future Phase attempting to execute
 * @returns Error message if validation fails, null if valid to proceed
