/**
 * Seed the database.
 *
 * Idempotent: running it twice does not duplicate anything. Safe against a
 * database that already has real data, because every insert is keyed and
 * conflicts are ignored rather than overwritten.
 *
 * What gets seeded, and why:
 *
 *   • **Prime Intellect as an account, with its people.** Public research,
 *     every record confidence-graded and cited. See `people.ts`.
 *   • **A handful of named neoclouds** as supply-side accounts, so the supply
 *     pipeline is not an empty screen on first run.
 *   • **A worked example** of the thing PIG exists for: one capacity
 *     commitment, two allocations against it, and therefore a real margin
 *     number and a real idle-capacity alert on the dashboard.
 *
 * The example is clearly labelled, and the company buying is invented. Real
 * named companies appear here only with a source; commercial terms attached to
 * one would be a fabricated record about someone else's business. The same rule
 * `demo.ts` states, obeyed here too.
