feat(streaming): enforce typed completion queues

Browse source 
Replace the flat deferred list, priority scan, unload bypass, and count-only execution cap with exact destination/control/unload/Near/Far FIFOs behind one typed frame meter. Price worker results before adoption, retain exact retry identity, reject stale generations without payload retention, and publish queue pressure through lifecycle diagnostics.

Tests: dotnet build AcDream.slnx -c Release --no-restore; dotnet test AcDream.slnx -c Release --no-restore (8138 passed, 5 skipped)

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.
measure CLR allocator overhead. `LandblockStreamer` exposes one allocation-free
single-consumer peek/read source so the update thread prices a result before
adopting it. `StreamingController` is the sole scheduler: it admits through the
typed meter into reusable destination/control/unload/Near/Far FIFOs, preserves
exact reference identity and retry position, rejects stale generations, and
executes every class through the same meter. Priority changes order, never the
budget. Lifecycle artifacts publish worker and per-class backlog, retained
bytes/age, yields, oversizes, overruns, and pending publication/retirement
facts. Publication remains transaction-atomic until Slice E4; retirement
quiesce/cursors belong to E3.
