Add test infrastructure with coverage and DB test skipping

- Create @reviq/test-helpers package with shared test utilities
- Add describeE2E helper that auto-prefixes test names with [e2e]
- Support SKIP_DB_TESTS=1 to skip database-dependent tests
- Add unix socket support for TEST_DATABASE_URL
- Add root commands: test:unit, test:all, test:cov, test:unit:cov
- Configure bunfig.toml to exclude dist/ from coverage reports
- Clean up tsconfig.json files to remove redundant settings
