fix(streaming): block login on complete world reveal

Browse source 
Make initial login and portal arrival consume one WorldRevealReadinessBarrier that joins near-tier mesh publication, destination composite uploads, and collision residency before normal world geometry becomes visible. This ports retail SmartBox's blocking-cell completion edge into the asynchronous client instead of exposing a ground-only login.

Add focused outdoor, indoor, texture, and invalid-claim tests; update the retail pseudocode, architecture, divergence record, issue ledger, roadmap baseline, and synchronized agent guidance.

### World-reveal readiness ownership
`WorldRevealReadinessBarrier` is the single App-layer owner of the edge that
allows normal world geometry to become visible at initial login or after a
portal. It joins `StreamingController`/`GpuWorldState` static-mesh publication,
`WbDrawDispatcher` composite-texture warmup, and `PhysicsEngine` destination
residency. Login's sky-only gate and portal-space transit consume the same
predicate; they differ only in presentation. Composite preparation advances
after `WbMeshAdapter.Tick` on the render thread, never from the streaming
worker. This is acdream's asynchronous equivalent of retail
`SmartBox::UseTime` holding position completion while
`CellManager::blocking_for_cells` is set.
### Teleport cell identity at the streaming boundary
The network and physics layers carry retail's complete `Position`: an
