DevOps: Builds, Tests, Documentation

[np-eazy]

node_modules is a pain in the ass that should be dealt with on both ends; we should configure GH Actions, Builds, and .gitignore to minimize diff transfers.

There shouldn't be much other work on the actual building of this project since it stems from a React app, but figure out the right line of testing for this app. A lot of it will have to be done by eye and actually playing the game, so this will come down to good overhead and documentation.

CoreState unit tests:

• Test idleMove collision mechanism
• Test activeMove collision mechanism
• Test rotate collision mechanism
• Test that moveTo moves to the right location and doesn't clip through blocks
• Test that lines get cleared properly
• Test that TargetBlocks get cleared properly

save this for after release, at this scale CI/CD is overkill. the very first one will probably only need a Google Domain and a Google Cloud build/deployment, and we can always scale later if people really do like the game
