feat(streaming): establish cost budget ledger

Browse source 
Add the validated frame-work profile, deterministic completion charges, and shadow admission meter before enforcing the scheduler in Slice E2. Lifecycle artifacts now expose elapsed work, would-yield limits, backlog bytes/age, and pending owner ledgers without changing accepted execution.

Tests: dotnet build AcDream.slnx -c Release --no-restore; dotnet test AcDream.slnx -c Release --no-build --no-restore (8124 passed, 5 skipped)

@ -708,6 +708,16 @@ replace state produced by another job. CPU mesh extraction may still be schedule
onto `ObjectMeshManager`'s thread-safe work queue, but the worker never publishes
partially hydrated cell membership or shell placement to the renderer.
`RuntimeOptions.StreamingWorkBudgets` is the single startup profile for
update-thread streaming cost. `StreamingWorkMeter` owns the frame-scoped
admission ledger; `LandblockStreamResultCost` assigns deterministic charges to
immutable completion arrays and logical retained entries without claiming to
measure CLR allocator overhead. During Slice E1 the ledger is observational:
the existing scheduler still executes its accepted work, while lifecycle
artifacts record would-yield limits, elapsed work, retained backlog bytes/age,
and pending publication/retirement counts. Enforcement belongs to the explicit
Slice E scheduler, not to presentation owners or the worker.
