fix(generators): emit cms barrel in feature template

The feature generator emitted no `src/integrations/cms/index.ts`, but
`gen job` and `gen event consume` both `assertAnchors` on that file's
`<gen:job-tasks>` anchor — so they failed on any freshly-scaffolded
feature. Add a `cms/index.ts.hbs` template carrying the anchor, wire the
add action into the generator, and export `./cms` from the package.json
template to match all five existing features.
