fix(security): validate URLs before network requests in arxiv tool and devtools

Apply validate_url() before fetching the arXiv API and PyPI polling
endpoints. Replace urllib.request.urlopen with requests.get to satisfy
bandit S310 without noqa suppressions. Update arxiv tool tests to mock
requests.get and validate_url.
