refactor(runtime): publish canonical entity object deltas

Issue stable Runtime identities at canonical registration, publish entity and inventory commits through one generation-stamped synchronous stream, and make graphical adapters borrow the same direct views and events as a no-window host. Preserve exact projection teardown and retail mutation order while removing App-side event reconstruction.

Make the hard-recenter ordering fixture independent of the production two-millisecond frame budget so its injected-failure gate is deterministic.
