### 🚀 The feature, motivation and pitch

### Motivation and Use Case
I'm currently working on integrating Yelay Action Provider AgentKit #741 , which supports multiple networks including Sonic (chainId: 146). However, I noticed that it's not listed within `typescript/agentkit/src/network/network.ts` and even if I import it to `CHAIN_ID_TO_NETWORK_ID` from `viem/chains` and try to test langchain_cdp_chatbot, I'm getting APIerror chain not supported.

What do you guys think about adding Sonic network support? It would enable developers to build more comprehensive cross-chain applications using AgentKit.

Would love to hear thoughts on this proposal and any guidance on how we might implement this support.
