OwnCord/scripts/run.mjs

#!/usr/bin/env node
// Root command facade (RL-04 / L-04).
//
// One entry point for the checks CI runs, so a contributor does not have to
// know which directory each stack lives in. `node scripts/run.mjs --list`
// prints every task and the exact commands it runs.
//
// Two rules this file exists to keep:
//
//   1. Cross-platform. No `make`, no shell syntax, no `cd &&`. Every step is
//      spawned directly with an explicit `cwd`, so there is no shell to quote
//      for and nothing that behaves differently on Windows.
//   2. The facade orchestrates, it never becomes the only path. Each step
//      prints the command it runs, in the directory it runs it in, so a
//      Go-only contributor can read the output and type those commands
//      instead — and never needs Node to work on the server.
//
// Dependency-free by design: Node's standard library only, like
// .superpowers/render-ledger.mjs. Adding a dependency here would mean
// `npm run check` could not run until `npm install` had.
