feat(packages): add monorepo support to package manager

- Registry now supports 'path' field for packages in monorepos
- Install function clones monorepo to cache, copies specific package
- Update function handles monorepo packages by re-syncing from cache
- Updated bundled registry to point to lumacs/packages monorepo

This allows all official packages to be hosted in a single repository
while still being installed individually.
