0.21.0.6 - Fix Crash (All Platforms)

A very similar update shipped to windows in October, but had issues with Linux / Mac / Android builds, that are resolved now. This ships the update to those other platforms, with a slight bump in the go version for good measure.

• Upgrade to golang v1.27.3.
• Fix regression where the game would always crash on recent versions when clicking the Zap! button.
• Fix bug since 0.21.0.0 where in some cases, late game saves would cause the game to hang forever during offline calculations.
