TechDebt - get actions to deploy from manifest, not filesystem

[purplecabbage]

In order to decide what actions to deploy, we iterate over the filesystem folders, this made a bit more sense before when the dist folder was cleared before any builds, and whatever build artifacts were left is what got deployed. Now we have a hash list of what we have deployed, so we don't constantly clean out dist.
This would make more sense if we iterated over what was built ( from the manifest ) instead of what exists on file.
