Add automatic discovery of CLI modules from project dependencies

The CLI now scans the project root's dependencies and devDependencies
for packages with the cli-module role, loading them automatically.
Falls back to the built-in set with a deprecation warning when no
modules are found. Updated create-app templates and the monorepo root
to include all CLI modules as explicit devDependencies.
