design gap: missing rule inputs

[jonahbeckford]

Before cram tests we had CommonsBase_Build.CMake0.Phony@3.25.3 in etc/dk/v/CommonsBase_Build/CMake0.Phony.values.jsonc which had the following note:

// USAGE: This is not meant to be called by end-users. It exists only because
// dk0 does not yet have static input dependencies for rules, so during `dk0 distribute`
// there is no way to distribute the CMake0.Bundle values (`dk0 distribute` correctly only exports
// objects and script modules). In fact, the lack of declaring rule inputs is a design gap
// that must be fixed before dk0 moves to arrows. So, "declareoutput" should be renamed to
// "declare" (?) and input assets/objects added to it. Of course, rules can still create whatever
// assets/objects they want, but any outside interaction (inputs and outputs to the rule) must
// be declared.

cram tests remove the need for Phony objects, but having to list each asset in a cram test widens the public interface of a distribution unnecessarily.
