fix: harden metrics boot and updater package-manager detection

[rafaelscosta]

Summary

• lazy-load metrics-only quality modules so missing .aiox-core/quality/ no longer breaks general CLI boot
• make aiox update detect the project's package manager from packageManager or lockfiles before add/remove
• add regression coverage plus a hotfix story for issues CLI broken on boot: aiox-core@5.2.9 published without quality/ directory (metrics-collector + seed-metrics) #782 and aiox update fails on pnpm/yarn projects — runs npm install in project root #785

Validation

• npm test -- --runTestsByPath tests/core/cli-metrics-resilience.test.js tests/installer/dependency-installer.test.js tests/updater/aiox-updater-package-manager.test.js tests/updater/aiox-updater.test.js --runInBand
• npm run lint
• npm run typecheck
• npm test -- --runInBand --forceExit --silent
• npm run validate:manifest
• node bin/aiox.js doctor
• cd pro && npm run validate:publish-surface

Issues

• Fixes CLI broken on boot: aiox-core@5.2.9 published without quality/ directory (metrics-collector + seed-metrics) #782
• Fixes aiox update fails on pnpm/yarn projects — runs npm install in project root #785
