When HTTP_PROXY / HTTPS_PROXY / ALL_PROXY environment variables are set,
CDP connections to localhost/127.0.0.1 can be incorrectly routed through
the proxy (e.g. via global-agent or undici proxy dispatcher), causing
browser control to fail.
Fix:
- New cdp-proxy-bypass module with utilities for direct localhost connections
- WebSocket (ws) CDP connections: pass explicit http.Agent to bypass any
global proxy agent patching
- fetch-based CDP probes: wrap in withNoProxyForLocalhost() to temporarily
set NO_PROXY for the duration of the call
- Playwright connectOverCDP: wrap in withNoProxyForLocalhost() since
Playwright reads env vars internally
- 13 new tests covering getDirectAgentForCdp, hasProxyEnv, and
withNoProxyForLocalhost (env save/restore, error recovery)
