Fixed 3 failing tests after P0-R1 normalization implementation:
- workflow-validator-comprehensive.test.ts: Updated expectations for normalized node type lookups
- handlers-n8n-manager.test.ts: Updated createWorkflow test for normalized input
- workflow-validator.ts: Fixed SplitInBatches detection to use short-form node types
All tests now passing. Node types are normalized to short form before validation,
so tests must expect short-form types in assertions.
