Move the canonical WorldSession generation, connect/enter/tick/stop transaction, inbound subscription owner, and retryable teardown acknowledgements into AcDream.Runtime. Keep App as a borrowing graphical host with a single inertable command projection and no mirrored session state.
Validated by 79 Runtime tests, 3,776 App tests with three existing skips, the Release solution build, and 8,428 complete Release tests with five existing skips.

Reduce GameWindow.OnUpdate to one typed orchestration call and remove transitive window callbacks from teardown, liveness, teleport placement, live presentation, auto-entry, and entity packet routing. Preserve the frozen retail object/network order while making the production owner graph explicit and testable.
