stack-modernization
Modernize a project's stack — outdated dependencies, dead/unused packages, deprecated packages, and framework-pattern drift (old patterns lingering after a major upgrade). Verifies the current latest of each package before proposing an upgrade, then applies changes incrementally with tests between each. Use when asked to update dependencies, modernize the stack, remove dead packages, or migrate stale framework patterns, across frontend and backend.
