test: build comprehensive test suite reaching 80%+ coverage threshold
Add 22 test files (~700 tests) covering security-critical modules, core
infrastructure, API routes, and error handling. Final coverage: 86.73%
statements / 80.57% branches / 85.57% functions / 87.42% lines, all above
the 80% threshold enforced by jest.config.js.
Highlights:
- Unit tests for crypto-utils, credential-manager, auth-manager, csrf,
input-validator, state-manager, health-checker, backup-manager,
update-manager, resource-monitor, app-templates, platform-paths,
port-lock-manager, errors, error-handler, pagination, url-resolver
- Route tests for health, services, and containers (supertest + mocked deps)
- Shared test-utils helper for mock factories and Express app builder
- npm scripts for CI: test:ci, test:unit, test:routes, test:security,
test:changed, test:debug
- jest.config.js: expand coverage targets, add 80% threshold gate
- routes/services.js: import ValidationError and NotFoundError from errors
- .gitignore: exclude coverage/, *.bak, *.log
