refactor(runtime): expose canonical gameplay state

Move character options and movement skills into the Runtime-owned character graph, expose borrowed inventory, character, and social views, and route retained UI state commands through generation-gated typed Runtime contracts. Preserve the existing synchronous wire path while deleting the App-owned option and skill mirrors and extending normalized parity checkpoints.
