feat(plugins): load activation scope from plugin manifest

Plugins can now declare activationScope ("app" | "project") in their
manifest; loader/runtime honor it to defer activation of project-scoped
plugins until a project is focused instead of activating everything at
app bootstrap. Bumps sdk/IdeaSDK to the commit that adds the field.
