Node.js 22.21.0+ and 24.5.0+ support proxy configuration natively
via NODE_USE_ENV_PROXY=1 and --use-env-proxy, making the legacy
global-agent and undici proxy workarounds unnecessary.
Rather than removing the function immediately, deprecate it with
context-aware runtime warnings that guide users based on their
current configuration:
- Users with GLOBAL_AGENT_* vars are told to switch to standard
HTTP_PROXY/HTTPS_PROXY and set NODE_USE_ENV_PROXY=1.
- Users with HTTP_PROXY/HTTPS_PROXY but no NODE_USE_ENV_PROXY are
told to set it.
- Users who have already opted in to Node.js built-in proxy see no
warning, and the legacy bootstrap is skipped entirely.
