Merge 69bd45ff made GameCult.Caching.MessagePack reference CultMath
(PackageId GameCult.Math), so its nuspec depends on GameCult.Math 0.2.4.
The packer's hand-written project list never packed it, and GameCult.Math
is not on nuget.org, so every clean consumer of the local feed failed
restore with NU1101. That is the Eve surface consumer smoke in the
"one-command multiplayer onboarding" jobs, red on both OSes since then.
The packer now walks ProjectReference from the public roots (GameCult.Mesh,
GameCult.Networking.WebSockets) and packs the whole closure. The expected
package names come from MSBuild's PackageId and Version for each project,
since GameCult.Math carries its own identity.
