/**
 * BLOCK R4 — Docs sweep smoke checks.
 *
 * Verifies the "web-first, terminal-fallback" treatment is in place:
 *
 *  1. README.md contains no `ssh root@gluecron.com` and no
 *     `bun run scripts/` references outside `<details>` blocks.
 *  2. DEPLOY.md has a "Day-to-day operations" section that points
 *     at `/admin/ops`.
 *  3. `docs/terminal-debt.md` exists and is non-empty.
 *
 * No mocks — pure filesystem reads.
