Per dev intent: don't mask JIT errors. Remove (jit-exclude! "host/*" "dream-*"
"dr/*") so ALL request-path SX runs under JIT. Host handlers miscompile on first
call in the http-listen path (map/rest arg bug → 500, self-heals on retry); that
surfacing is the point — it exercises the JIT against real durable-IO traffic and
gives the sx-vm-extensions loop the full miscompile list to fix (kernel bugs A/B
in plans/HANDOFF-jit-miscompile.md). Datalog JIT win stays (/tags fast).
