Bun's fetch and node:http honor HTTP_PROXY/HTTPS_PROXY env vars, which can route loopback traffic through a configured proxy (e.g. Surge/Clash). When NO_PROXY doesn't explicitly exclude localhost, this breaks loopback communication: SessionStart hooks fail to arrive (transcripts don't sync, web UI stays empty), runner control client times out, and MCP server connections fail. Normalize NO_PROXY at the CLI entrypoint to always cover loopback (localhost, 127.0.0.1, ::1). Child processes inherit the patched env so their loopback traffic is covered too. Non-loopback traffic continues using the configured proxy. Supersedes the runner control client workaround from #563.
