Allow explicitly enabled installed plugins to register declared trusted tool policies and agent tool result middleware, with trusted policy ids scoped by plugin owner.\n\nVerification covered targeted plugin/agent tests, typecheck, build, lint, local autoreview, and a Blacksmith Testbox runtime proof (tbx_01ktr1nq0rhq47fjkwrepm7fd3).
Reuse the startup runtime plugin registry across provider/tool helper paths while preserving standalone CLI/MCP fallback loading.
Includes follow-up fixes for migration/provider/tool registry bootstrap and regression coverage for compatible registry reuse.

Simplify plugin installation and runtime loading around package-manager-owned dependencies, with Jiti reserved for local/TS fallback paths.
Also scans npm plugin install roots so hoisted transitive dependencies are covered by dependency denylist and node_modules symlink checks.
