fix(hub): forward host HTTP(S)_PROXY into agent sandbox (v0.0.39)

Host egress requires the local forward proxy; sandbox env previously
omitted PROXY vars so Bash/curl timed out on public image URLs. Pass
HTTP(S)/ALL/NO_PROXY (+ lowercase) and NODE_USE_ENV_PROXY from the
trusted service environment into the agent subprocess.
