feat: add identify field support to swarm.peers API (#342)

* feat: add identify field support to swarm.peers

includes the Identify object from the swarm/peers API response when the identify option is set to true. this enables consumers to access peer information like AgentVersion, Protocols, and PublicKey.

* test: add test coverage for identify field in swarm.peers

- add test case for swarm.peers with identify option
- update TypeScript types to include identify field
