Repo-health cleanup from an external code audit:
- eslint: ignore src/_archived (already excluded by tsconfig, so linting it only
produced 6 parserOptions.project errors).
- Align the architecture claim: src/index.ts and docs said "12"/"6" bounded
contexts; there are 13 domain dirs (matching package.json). Updated src/index.ts
(comment + ARCHITECTURE const) and the docs list to the actual 13.
- Apply stock `eslint --fix` (prefer-const, prefer-as-const, no-useless-escape,
no-regex-spaces) across 24 files.
Lint problems: 1072 -> 1031. Typecheck and build pass; no behavioral changes.
