docs(14): create phase plans for parallel phase execution

Phase 14: Parallel Phase Execution
- 8 plans in 5 waves
- 4 parallel in Wave 1, 3, 5
- Adds phase_dependencies schema (mirrors task_dependencies)
- PhaseDispatchManager port and adapter
- tRPC procedures and CLI commands
- Unit tests and E2E tests

+Add tRPC procedures for phase dependencies and dispatch.

+Purpose: Expose phase dependency and dispatch operations via API.
+Output: tRPC procedures for creating dependencies and managing phase queue.

+Import PhaseDispatchManager from dispatch module.

+Add procedures under existing phase group:
+
+createPhaseDependency:
+- input: { phaseId: string, dependsOnPhaseId: string }
+- validates both phases exist
+- calls phaseRepository.createDependency()
+- returns { success: true }
+
+getPhaseDependencies:
+- input: { phaseId: string }
+- returns { dependencies: string[] } from phaseRepository.getDependencies()
+
+Add new phase dispatch procedures:
+
+queuePhase:
+- input: { phaseId: string }
+- requires phaseDispatchManager
+- calls phaseDispatchManager.queuePhase()
+- returns { success: true }
+
+dispatchNextPhase:
+- no input
+- requires phaseDispatchManager
+- calls phaseDispatchManager.dispatchNextPhase()
+- returns PhaseDispatchResult
+
+getPhaseQueueState:
+- no input
+- requires phaseDispatchManager
+- returns queue state
+
+Follow existing router patterns for error handling and input validation.
