feat(runtime): define borrowed views commands and ordered events

Establish the J1 presentation-independent contract with instance-scoped clocks and generations, immutable borrowed views, typed generation-gated commands, normalized ordered diagnostics, and teardown acknowledgements. Route graphical startup plus press-time selection, movement, and combat through focused App adapters over the exact existing owners without adding a queue or mirrored world.

Validated by the Release solution build, 13 Runtime tests, 3,838 App tests with three existing skips, and the complete 8,424-test Release suite with five existing skips.
