FEATURE REQUEST: add proxy option when generating client code

i d like to add a feature that when importing a curl request it recognizes proxy header in curl --socks5-hostname and generates client code with proxy in it.

example
input
```curl --socks5-hostname localhost:9050 https://example.com```

output
```
import requests

url = "https://example.com"
payload = ""
headers = {}
proxies = {
'http': 'socks5://localhost:9050',
'https': 'socks5://localhost:9050',
}

response = requests.request("GET", url, data=payload, headers=headers, proxies=proxies)
```

Start by tracing how curl imports are parsed and how the Python requests client output is generated. Reproduce the shown --socks5-hostname input, then verify that the generated requests code includes the proxy configuration while preserving the existing URL and request details. No file or test is named in the issue.
