Chess

Made some improvements to Based Chess ♟️!

- Onchain-ification. Game state can be synced or checkpointed onchain on Base, which can be verified by any 3rd party. Once a player wins a game, automatic verification by Based Chess occurs and the winner can mint a GameWin NFT 🏆 
- Farcaster integration: invite and see friends using Farcaster username and pfp; Add Based Chess mini app w/ notifications on and get notified when someone invites you to a game; using @neynar APIs
- Game specific embed images showing game results and players when sharing a link to a game
- UI/UX cleanup all around
