Use shorter alias for package names

Some package names are too long. (e.g. primitives)
It hurts code readability while importing and using the package that has a long name.

Use alias for long package name like `prims` for `primitives`

Start by locating imports and usages of the long package name, especially the `primitives` example mentioned in the issue. Check how package aliases are currently written and verify that the chosen shorter alias compiles wherever the package is imported. Done means long package references are replaced consistently without breaking the SDK.
