docs(runtime): close cost-budgeted streaming slice

Browse source 
Record the exact physical-display evidence, ownership fixes, budget semantics, and performance deltas that close Slice E. Reconcile the architecture, roadmap, milestones, issues, documentation map, and session instructions before the explicit F/G approval gate.

Production world-mesh streaming now consumes the validated machine-local

lifetime, full-suite, and user-visual gates passed. Process allocation fell
41.8–61.9%, GC pause time fell 48.4–54.1%, uncapped CPU/GPU p99 improved
17.0%/20.6%, and invalid Setup-probe exceptions fell to zero. Slice D unified

generation now owns one exact destination reservation across every typed
