Description

package validate doesn't report dependencies that spans multiple major versions. A dependency constraint like this will pass package validate

"gren-lang/core": "1.0.0 <= v < 3.0.0"

Even though such a constraint will fail when the package is downloaded as part of the compile step

Research direction

Start at the package validate command and trace how dependency constraints are checked before the compile step. Reproduce the gren-lang/core constraint spanning versions 1.0.0 through 3.0.0; done means validation reports it instead of allowing a later download failure.
