Serve the upstream malformed chunk sequence and infinite redirect loop
instead of returning Python source. Preserve redirect parameters and origin,
explicit raw body writes, and supported endpoint filtering.
Validation: all 550 benchmark tests pass, including raw wire and partial
HTTP body decoding regressions. With the same Moli binary, 88 focused WPT
cases improve from 77 to 82 passes (127 to 132 of 143 subtests).
The corrected fixture also exposes a page XHR bug: malformed-body handling
now times out instead of failing on unexpected load. Its streaming failure
branch records the network error without dispatching XHR error/loadend;
that engine fix follows separately. The worker variant now passes.
