Solana transaction support

[SurgeCode]

Adds solana support through wallet connect

• Still needs work but can take review on non nits aka general approach
• Solana transaction primitive is also drafted out but needs testing PR

minimal implementation example

import { BitteAiChat } from 'bitte-ai-chat';
import { useAppKitConnection, Provider } from '@reown/appkit-adapter-solana/react';
import { useAppKitProvider } from '@reown/appkit/react';

const App = () => {
  // Get Solana connection and wallet provider
  const { connection } = useAppKitConnection();
  const { walletProvider } = useAppKitProvider<Provider>('solana');

  return (
    <BitteAiChat
      // Required agent configuration
      agentData={{
        id: "your-agent-id",
        name: "Agent Name",
        description: "Agent Description",
      }}
      // Solana wallet configuration
      solanaWallet={{
        connection,
        provider: walletProvider
      }}
      apiUrl="/api/chat"
    />
  );
};

export default App;
