Per Fasthei's CHANGES_REQUESTED on #15: deleting all sub/swarm docs left no tracking entry for the still-in-development swarm capability. Adds docs/integration/heicode-swarm-deferred.md stating HM does not implement swarm runtime, the old HM-orchestrated sub/swarm model is deprecated, new swarm work lives on AM/Swarm side, and a per-file migration mapping (deprecated / deferred / superseded) for all 11 deleted docs. Links it from docs/README.md so deletion no longer drops context. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
