Replace blanket `npm test` with lint-staged for linting/formatting and
a turbo --filter script that runs tests only for workspace packages
that have staged .ts/.tsx files.

Setup code quality tooling for the monorepo:
- ESLint 9 flat config with TypeScript, import ordering, and NestJS rules
- Prettier with consistent formatting across all files
- dependency-cruiser enforcing module boundary rules (no cross-module internals, no circular deps)
- Husky + lint-staged for pre-commit hooks
- Auto-fixed existing files for type imports and import ordering
