Cube Core v0.31 — YAML, Views, and Lambda

The Cube Core v0.31 release introduces several new features, including support for YAML data modeling, ksqlDB as a data source, and Lambda pre-aggregations. Breaking changes include foreign cube references requiring a cube member and the shownproperty hiding cubes/views from the metaendpoint when set to false. The release also adds views, a new driver for Firebolt and Trino, and improvements to the SQL API, allowing it to connect to more downstream tools such as Appsmith, Tableau, and Microsoft PowerBI.
