Merge master into dev/4.11.x and preserve plugin runner architecture

Reconcile migration branches without rewriting published revisions; retain additive Codex, monitoring, provider and platform fixes. Keep dynamic runner schemas and Host ownership, restore compatibility regressions, and preserve safe model-test error handling.
