9e1a4129c0 feat(tests): implement Phase 2 integration testing - workflow creation tests
Implements comprehensive workflow creation tests against real n8n instance
with 15 test scenarios covering P0 bugs, base nodes, advanced features,
error scenarios, and edge cases.

Key Changes:
- Added 15 workflow creation test scenarios in create-workflow.test.ts
- Fixed critical MSW interference with real API calls
- Fixed environment loading priority (.env before test defaults)
- Implemented multi-level cleanup with webhook workflow preservation
- Migrated from webhook IDs to webhook URLs configuration
- Added TypeScript type safety fixes (26 errors resolved)
- Updated test names to reflect actual n8n API behavior

Bug Fixes:
- Removed MSW from integration test setup (was blocking real API calls)
- Fixed .env loading order to preserve real credentials over test defaults
- Added type guards for undefined workflow IDs
- Fixed position arrays to use proper tuple types [number, number]
- Added literal types for executionOrder and settings values

Test Coverage:
- P0: Critical bug verification (FULL vs SHORT node type format)
- P1: Base n8n nodes (webhook, HTTP, langchain, multi-node)
- P2: Advanced features (connections, settings, expressions, error handling)
- Error scenarios (documents actual n8n API validation behavior)
- Edge cases (minimal workflows, empty connections, no settings)

Technical Improvements:
- Cleanup strategy preserves pre-activated webhook workflows
- Single webhook URL accepts all HTTP methods (GET, POST, PUT, DELETE)
- Environment-aware credential loading with validation
- Comprehensive test context for resource tracking

All 15 tests passing 
TypeScript: 0 errors

1728495146 fix: address critical code review issues
Fix security and reliability issues identified in code review:

1. Security: Remove non-null assertions in credentials.ts
   - Add proper validation before returning credentials
   - Throw early with clear error messages showing which vars are missing
   - Prevents runtime failures with cryptic undefined errors

2. Reliability: Add pagination safety limits
   - Add MAX_PAGES limit (1000) to all pagination loops
   - Prevents infinite loops if API returns same cursor repeatedly
   - Applies to: cleanupOrphanedWorkflows, cleanupOldExecutions, cleanupExecutionsByWorkflow

Changes ensure safer credential handling and prevent potential infinite loops
in cleanup operations.

2305aaab9e feat: implement integration testing foundation (Phase 1)
Complete implementation of Phase 1 foundation for n8n API integration tests.
Establishes core utilities, fixtures, and infrastructure for testing all 17 n8n API handlers against real n8n instance.

Changes:
- Add integration test environment configuration to .env.example
- Create comprehensive test utilities infrastructure:
  * credentials.ts: Environment-aware credential management (local .env vs CI secrets)
  * n8n-client.ts: Singleton API client wrapper with health checks
  * test-context.ts: Resource tracking and automatic cleanup
  * cleanup-helpers.ts: Multi-level cleanup strategies (orphaned, age-based, tag-based)
  * fixtures.ts: 6 pre-built workflow templates (webhook, HTTP, multi-node, error handling, AI, expressions)
  * factories.ts: Dynamic node/workflow builders with 15+ factory functions
  * webhook-workflows.ts: Webhook workflow configs and setup instructions

- Add npm scripts:
  * test:integration:n8n: Run n8n API integration tests
  * test:cleanup:orphans: Clean up orphaned test resources

- Create cleanup script for CI/manual use

Documentation:
- Add comprehensive integration testing plan (550 lines)
- Add Phase 1 completion summary with lessons learned

Key Features:
- Automatic credential detection (CI vs local)
- Multi-level cleanup (test, suite, CI, orphan)
- 6 workflow fixtures covering common scenarios
- 15+ factory functions for dynamic test data
- Support for 4 HTTP methods (GET, POST, PUT, DELETE) via pre-activated webhook workflows
- TypeScript-first with full type safety
- Comprehensive error handling with helpful messages

Total: ~1,520 lines of production-ready code + 650 lines of documentation

Ready for Phase 2: Workflow creation tests
