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)

**Checkpoint 2026-07-24:** E0 fixed the retail/adaptation contract and current

completion charge model, plus lifecycle-artifact shadow diagnostics while
preserving the prior scheduler's execution. E2 is the first enforcement
cutover.
**Purpose:** Remove update-thread portal transactions.
- Introduce explicit stage queues and `StreamingWorkBudget`.

**Complete 2026-07-24.** `RuntimeOptions` now owns one validated scheduling
profile (time, admissions, retained CPU bytes, entity operations, requested GPU
bytes, GL retire operations, and destination reserve). The single-thread meter
has a deterministic clock seam, first-operation progress rule, explicit
yield/oversize/failure/overrun facts, and no effect on legacy execution at this
checkpoint. Immutable completion payloads receive deterministic charges for
their exact array data and logical retained entries; this is deliberately not
misreported as CLR heap size. Lifecycle JSON now includes last-frame work,
deferred retained bytes/age, and pending publication/retirement counts.

### E2 — Explicit admission queues
- Replace `_deferredApply` with stable generation/priority queues.
