pingqiu 512bb5bcf6 fix: orchestrator owns full catch-up contract (budget + truncation) ...

CompleteCatchUp now integrates:
- BeginCatchUp with start tick (freezes target)
- RecordCatchUpProgress (skips if already converged, e.g., truncation-only)
- CheckBudget at completion tick (escalates to NeedsRebuild + logs)
- RecordTruncation before completion (logs truncation_recorded)
- Logs causal reason for every rejection/escalation

CatchUpOptions: StartTick/CompleteTick (separate) + TruncateLSN.

3 new orchestrator-level tests:
- ReplicaAhead_TruncateViaOrchestrator: truncation through entry path
- ReplicaAhead_NoTruncate_CompletionRejected: logs completion_rejected
- BudgetEscalation_ViaOrchestrator: budget violation → NeedsRebuild + logs

Observability tests relabeled as sender-level (not entry-path).
