DSH GoalMesh

Installable DeepSeek Harness composition bundle. It inserts the invariant registry, GoalMesh Host tool, its invariant companion, and the Web trajectory companion as one self-contained configuration layer.

The bundle implements the v0.3 foreground DAG scheduler, dependency and failure-mode policies, local nested swarms with child-scoped leases, durable trajectory, trajectory invariant, and Web Agent tree as one installable composition. Its default patch enables nestedMode: local-only with the in-process spawn provider.
