feat: Phase 12 P3+P4 — diagnosability surfaces, perf floor, rollout gates
P3: Add explicit bounded read-only diagnosis surfaces for all symptom classes:
- FailoverDiagnostic: volume-oriented failover state with per-volume
DeferredPromotion/PendingRebuild entries and proper timer lifecycle
- PublicationDiagnostic: two-read coherence check (LookupBlockVolume vs
registry authority) with computed Coherent verdict
- RecoveryDiagnostic: minimal ActiveTasks surface (Path A)
- Blocker ledger: 3 diagnosed + 3 unresolved, finite, from actual file
- Runbook references only exposed surfaces, no internal state
P4: Add bounded performance floor + rollout-gate package:
- Engine-local floor measurement with explicit IOPS gates per workload
- Cost characterization: WAL 2x write amp, -56% replication tax
- Rollout gates with semantic cross-checks against cited evidence
(baseline numbers, transport/network matrix, blocker counts)
- Launch envelope tightened to actually measured combinations only
