Sprint 65: Parallel Pair Upgrades and Queue Optimization — Steps 879-888

Implements priority-aware pair-upgrade queue with starvation prevention:
- PairUpgradeQueue: enqueue/dequeue/getActive sorted by priority (step 879)
- UpgradePriorityPolicy: critical/revenue/coverage/experimental classes (step 880)
- ParallelDispatchOptimizer: schedule N pairs with blocked-pair constraints (step 881)
- StarvationPrevention: detect and promote starved pairs (step 882)
- QueueHealthScorer: stall-rate-based health scoring (step 883)
- RetryBackoffStrategy: exponential backoff with max-attempts guard (step 884)
- whetstone_enqueue_pair_upgrade MCP tool (step 885)
- whetstone_get_upgrade_queue MCP tool with priority sorting (step 886)
- UpgradeQueueObservabilityPanel: snapshot model for queue visibility (step 887)
- Sprint65IntegrationSummary (step 888)

All 10 steps passing (94 tests). Routing rule: critical-tier regressions
preempt all experimental upgrades.
