Add phase dependencies to database schema and repository following the task_dependencies pattern.

Purpose: Enable tracking which phases depend on which other phases, prerequisite for parallel execution. Output: phase_dependencies table, PhaseRepository with dependency methods.

Task 1: Add phase_dependencies table to schema src/db/schema.ts Add phase_dependencies table mirroring task_dependencies: - id (text, primary key) - phaseId (text, FK to phases.id, cascade delete) - dependsOnPhaseId (text, FK to phases.id, cascade delete) - createdAt (integer timestamp)

Add relations for phases:

• dependsOn: many(phaseDependencies, relationName: 'dependentPhase')
• dependents: many(phaseDependencies, relationName: 'dependencyPhase')

Add phaseDependenciesRelations with:

• phase: one(phases, dependentPhase)
• dependsOnPhase: one(phases, dependencyPhase)

Export PhaseDependency and NewPhaseDependency types. npx tsc --noEmit passes phase_dependencies table defined with proper FK relations and types exported

Task 2: Add dependency methods to PhaseRepository src/db/repositories/phase-repository.ts, src/db/repositories/drizzle/phase.ts Add to PhaseRepository interface: - createDependency(phaseId: string, dependsOnPhaseId: string): Promise - getDependencies(phaseId: string): Promise (returns IDs of phases this phase depends on) - getDependents(phaseId: string): Promise (returns IDs of phases that depend on this phase)

Implement in DrizzlePhaseRepository:

• createDependency: insert into phase_dependencies with nanoid
• getDependencies: select dependsOnPhaseId where phaseId = input
• getDependents: select phaseId where dependsOnPhaseId = input

Follow exact patterns from DrizzleTaskRepository.createDependency. npx tsc --noEmit passes; npm test -- --grep "phase" passes PhaseRepository has dependency methods, Drizzle adapter implements them

Before declaring plan complete: - [ ] `npm run build` succeeds without errors - [ ] `npm test` passes all tests - [ ] Phase dependency types exported from schema - [ ] PhaseRepository interface has 3 new methods - [ ] DrizzlePhaseRepository implements all methods

<success_criteria>

• All tasks completed
• All verification checks pass
• Schema matches task_dependencies pattern
• Repository follows hexagonal architecture </success_criteria>

After completion, create `.planning/phases/14-parallel-phase-execution/14-01-SUMMARY.md`
