HUX-04/HUX-08: after a successful tool execution the hux-runtime plugin
now registers freshly written files as typed artifacts (create or
immutable version by conversation-scoped title, bounded to 1 MiB,
deterministic idempotency keys) and records up to three deduplicated
web sources from real network/web_search output. Emitters are fail-open
and can never break the tool result. Delivered through the plugin
ConfigMap; 95% branch coverage; quality contract updated.
