Ethereum Account Abstraction

i spent the last week rebuilding open browser wallet from scratch with the goal of being more of a blank canvas for a application-specific browser wallets

features
- built on wagmi + viem's account abstraction libraries
- it now has no styling whatsoever
- uses database backend by default with authenticated sessions (will have a standalone example in the future)
- connect to apps with Coinbase Wallet SDK, Mobile Wallet Protocol, and WalletConnect (wip)
- supports most common wallet features (sign messages, sign transactions, etc.)
- multichain support out the box

might refactor this into a library at some point but waiting to see which abstractions make sense
