=== Adopted Branch AgentRun Support - Implementation Summary ===

FEATURE: Added AgentRun creation and spec directory initialization to adopted branches

KEY CHANGES:

1. AdoptBranchUseCase (packages/core/src/application/use-cases/features/adopt-branch.use-case.ts)
   - Added IAgentRunRepository and ISpecInitializerService dependencies
   - Calculate feature number from existing features count
   - Conditional spec directory initialization (preserves existing specs)
   - Create AgentRun record with:
     * status = pending
     * prompt = "(adopted from existing branch)"
     * agentType from settings
     * threadId generated via randomUUID()
   - Link Feature.agentRunId to created AgentRun
   - Set Feature.specPath to spec directory path
   - Lifecycle logic unchanged (Review if PR exists, Maintain otherwise)

2. Test Coverage
   - Unit tests: 36 tests covering AgentRun creation, spec initialization, error handling
   - Integration tests: 7 tests covering adopt → start → resume flow

VERIFICATION:
All tests passing:
- AdoptBranchUseCase unit tests: ✓ 36 passed
- Adopt flow integration tests: ✓ 7 passed
- Full test suite: ✓ 569 tests passed (48 test files)

SUCCESS CRITERIA MET:
✓ Adopted features have valid AgentRun record linked via feature.agentRunId
✓ StartFeatureUseCase works with adopted features
✓ ResumeFeatureUseCase works with adopted features
✓ AgentRun has correct initial state (pending, agentType from settings, threadId)
✓ Spec directory initialized for adopted features without existing specs
✓ Existing spec directory preserved when already present
✓ Feature.specPath set correctly for both new and existing spec directories
✓ All existing tests pass without modification
✓ No breaking changes to existing feature creation flow
