feat(sdk): latest network proto + error handling + fix examples

[mattstam]

This PR updates the network SDK with:

• Updated proto
• Custom error types using thiserror (e.g. to implement different logic for unexecutable vs unfulfillable)
• Removal all unwrap / expect statements and bubble up all errors correctly
• Fix all examples / docs to borrow the stdin

Error handling example:

    // Handle errors from proof generation.
    let mut proof = match proof_result {
        Ok(proof) => proof,
        Err(e) => {
            if let Some(network_error) = e.downcast_ref::<Error>() {
                match network_error {
                    Error::RequestUnexecutable { request_id: _ } => {
                        eprintln!("Program is unexecutable: {}", e);
                        std::process::exit(1);
                    }
                    Error::RequestUnfulfillable { request_id: _ } => {
                        eprintln!("Proof request cannot be fulfilled: {}", e);
                        std::process::exit(1);
                    }
                    _ => {
                        eprintln!("Unexpected error: {}", e);
                        std::process::exit(1);
                    }
                }
            } else {
                eprintln!("Unexpected error: {}", e);
                std::process::exit(1);
            }
        }
    };

Example of error bubbling up and handling it:

In a real situation, you may want to retry if it's unfulfillable or implement custom logic.
