Implement DefaultPhaseDispatchManager adapter with in-memory queue and dependency checking.

Purpose: Enable actual phase dispatch with dependency resolution. Output: Working adapter implementation.

Task 1: Implement DefaultPhaseDispatchManager src/dispatch/phase-manager.ts Create DefaultPhaseDispatchManager class implementing PhaseDispatchManager:

Constructor dependencies:

• phaseRepository: PhaseRepository
• eventBus: EventBus

Internal state:

• phaseQueue: Map<string, QueuedPhase>
• blockedPhases: Map<string, {phaseId: string, reason: string}>

Implement methods:

• queuePhase: fetch phase, get dependencies from phaseRepository.getDependencies(), add to queue, emit PhaseQueuedEvent
• getNextDispatchablePhase: filter queue for phases with all deps complete (phase.status === 'completed'), sort by queuedAt
• dispatchNextPhase: get next, update phase status to 'in_progress', emit PhaseStartedEvent, return result
• completePhase: update phase status to 'completed', remove from queue, emit PhaseCompletedEvent
• blockPhase: update phase status, add to blocked map, remove from queue, emit PhaseBlockedEvent
• getPhaseQueueState: return current state of queued, ready, blocked

Private helper:

• areAllPhaseDependenciesComplete(dependsOn: string[]): check each phase status via phaseRepository.findById

Follow exact patterns from DefaultDispatchManager for consistency. npx tsc --noEmit passes DefaultPhaseDispatchManager implements all interface methods

Task 2: Export DefaultPhaseDispatchManager src/dispatch/index.ts Add export for DefaultPhaseDispatchManager class. npx tsc --noEmit passes DefaultPhaseDispatchManager exported from dispatch module Before declaring plan complete: - [ ] `npm run build` succeeds without errors - [ ] `npm test` passes all tests - [ ] DefaultPhaseDispatchManager importable from src/dispatch

<success_criteria>

• All tasks completed
• All verification checks pass
• Adapter follows hexagonal architecture pattern
• Event emission matches phase event types from 14-02 </success_criteria>

After completion, create `.planning/phases/14-parallel-phase-execution/14-04-SUMMARY.md`
