Release of CTBase v0.30.13 (stable): gradients with AutoMooncake at a view of a host array are now arrays (the CTBaseMooncake extension, Mooncake as a weak dependency), plus the pins of ct-agents and ct-conventions, the docs LOAD_PATH fix and the breakage suite deriving its consumers. No breaking change.

Changes: Project.toml (version), CHANGELOG.md (the [Unreleased] entries move under [0.30.13], with the two missing ones), BREAKING.md (non-breaking note).
