The Elegant project should be split up into more smaller packages as the complexity grows.

[Bowens20832]

The Elegant package is starting to get bloated with each release and update.

To reduce the bloat, I propose to break each core Elegant feature into separate package namespaces under the "packages" directory.

elegant-cli
├── .github
├── tests
├── packages
├── package.json
├── README.md
└── ...

Under packages would be:

packages
├── elegant-core
├── elegant-cms
├── elegant-docs
├── base-theme
├── docs-theme
├── blog-theme
├── resume-theme
├── portfolio-theme
├── event-theme

This change would migrate the existing code under source/elegant into packages/elegant.
