Phase 1 — Repository Setup

Step 1.1 — Create the monorepo. pnpm workspace with apps/web, apps/server, packages/sim, packages/schema, packages/content (all @deadhead/*), strict tsconfig.base.json extended by each package. pnpm install + pnpm typecheck pass. Repo moved to C:\Projects\Deadhead Space Freight Tycoon (G: is exFAT, no symlinks).
Step 1.2 — Linting and formatting. ESLint 10 + typescript-eslint + Prettier at the root (pnpm lint, pnpm format). Purity rule bans Math.random, Date.now and argument-less new Date() in packages/sim and packages/content; verified it fails on a planted Math.random().
Step 1.3 — Test runner. Vitest 5 with one project per workspace package (pnpm test). Trivial smoke test in packages/sim/test/smoke.test.ts; 1 passing.
Step 1.4 — Continuous integration. Repo pushed to Gitea; .gitea/workflows/ci.yml runs install, typecheck, lint and test on every push (runner homelab-runner). Run #1 failed because Prettier scanned the runner's in-workspace .pnpm-store/; ignored it, and run #2 is green.
Step 1.5 — Local Postgres via Docker Compose
