HS: socket namespaced names + timeout plumbing (+2)

Native JS wrapper: replace SX dict with (host-new "Object") so
host-set! mutations persist for rpc and closed? updates. bind-path!
uses (host-new "Object") for intermediate namespace nodes so dotted
paths like MyApp.chat bind correctly. Fix _hs_make_rpc_proxy call
wrapper to strip the nil this-arg. Land tests 4+16: namespaced sockets
work, with timeout parses and uses the configured timeout. 5/16 total.
