Two improvements:
1. ISE scan ordering — engram_scan_nodes_by_type_json now sorts InternalStateEvent
nodes by created_at DESC (most-recent-first) instead of salience DESC. Old
high-salience ISEs (session-start, wm-promotion) no longer dominate offset 0,
burying recent heartbeat and curiosity_scan events at offsets 20000+. New
behavior: ?limit=10 returns the 10 most recent ISEs regardless of salience.
All other node types retain existing salience-sorted behavior.
2. http_serve_async registered as elc builtin — added to builtin_arity() in both
codegen.el (EL compiler source) and dist/platform/elc.c (compiled C). Also
rebuilt elc binary from updated elc.c. This closes the fragile-patch gap from
2026-05-21: elc previously treated http_serve_async as an unknown identifier,
and the gap description noted elc would 'silently revert to blocking http_serve'
on next soul rebuild. Now http_serve_async has a proper 2-arg arity entry and
will survive all future soul recompiles without a manual neuron.c patch.
