So that we get auto-formatting and syntax checking in our code editor. The only snippets which have not been extracted are either terminal output, or file fragments (e.g. CUE) which are not valid standalone files. Resolves https://github.com/dagger/dagger/issues/1715 While at it, do a few fly-by improvements: - beta.1 -> beta.2 - add CUE & BuildKit links - up -> do Signed-off-by: Gerhard Lazu <gerhard@lazu.co.uk>

Dagger CUE API (0.2+)
As of Dagger 0.2 (codename Europa), the Dagger CUE API can be imported at dagger.io/dagger.
The Dagger CUE API is the set of CUE packages released alongside the Dagger engine, to allow developers to access its features.
Plan definition
#Plan defines the structure of a Dagger plan - a complete configuration executable by dagger do.
Core types
Dagger extends the CUE type system with the following core types:
#FS: a reference to a filesystem tree#Secret: a secure reference to an external secret#Servicea reference to a network service endpoints
Core actions
Dagger works by executing actions in a certain order and passing data between actions in a certain layout.
Developers can combine actions into higher-level actions, which in turn can be combined into even higher-level actions, and so on at arbitrary levels of depth. At the bottom of this abstraction stack are core actions: these are implemented by Dagger itself, and are always available.
The following core actions are available:
| Core action | File | Description |
|---|---|---|
#Exec |
exec.cue | Execute a command in a docker-compatible container |
#HTTPFetch |
