[CLAUDE] Skill: adopt Harness-8 all-inherit (11 sub -> inherit, go two-tier H4) + email-back ai_infra

AI_INFRA broadcast 2026-06-16 (BAT BUOC, PROJECT-FIT 6/6). Flip 7 demoted subs claude-opus-4-8 -> inherit (all 11 inherit; SE has no cheap helper/gopher); agents/README + hmw.js comments codify (resolveModel defers frontmatter). adap-report + email-back (content_sha256 fa7f690d round-trip MATCH). Nac executed-file VERIFIED-pending-restart (frontmatter no hot-reload). Runtime unchanged now (inherit=Opus 4.8 1M since Fable suspended H5); forward-looking + H5.6 restore simpler.
