/**
 * `pnpm run deploy` / `pnpm run deploy:dev` — the one deploy path.
 *
 * 1. Build the app for the env (`CLOUDFLARE_ENV=<env> pnpm run build`), which
 *    renders `dist/server/wrangler.json` from the tracked `wrangler.jsonc`.
 * 2. If `wrangler.generated.<env>.json` exists, overlay the fields it owns (vars,
 *    D1 id, sender allow-list, custom-domain route) onto that built config, print
 *    every value it changed and every structural field it was NOT allowed to
 *    change, then re-read the file and fail if it does not carry them.
 * 3. `wrangler deploy --config dist/server/wrangler.json`.
 *
 * Before this, `deploy:dev` ran `wrangler deploy --env dev` against the tracked
 * config and never read the generated file, so a value `setup:sending` wrote
 * there (MAIL_SENDING_DOMAINS) never reached the Worker — silently.
 *
 * `--dry-run` does steps 1–2 for real (local files only) and passes `--dry-run`
 * to wrangler, which bundles and prints the bindings without uploading.
 *
 * Usage:
 *   pnpm run deploy:dev              # env dev
 *   pnpm run deploy:dev --dry-run
 *   pnpm run deploy                  # top-level (production) config
