Implement Brian for General Agent

Based on its functionalities, it seems like it would allow general agents to do a lot of stuff:

Their SDK is Typescript-only (why ?!), but they also have API.

> /transaction: get executable transactions from a prompt.

This one, for example, sounds like something that @gabrielfior implemented for Omen in Olas' mechs.

We could investigate this to see what the agent should call/prompt to execute actions on-chain, e.g. do swaps.

I have already played with it a little, it works very nicely (for the simple stuff at least):

For the second task, it just popped up Metamask to confirm the swap.
