fix(pilotctl): make appstore call timeout configurable (default 120s)

appstore call hardcoded an 8s socket read deadline, which cut off any
legitimately slow method (multi-step research, cold LLM synthesis) long
before it could return — surfacing as a spurious 'i/o timeout' even though
the app and backend were healthy. Default to 120s and allow per-call
--timeout / $PILOT_APPSTORE_CALL_TIMEOUT. The 8s was a reply deadline, not
a dial timeout; dialing the local socket stays fast.
