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.

Replace generic "Please try again later or contact support" error messages
with actionable guidance that directs users to use n8n_get_execution with
mode='preview' for efficient debugging.
## Changes
### Core Functionality
- Add formatExecutionError() to create execution-specific error messages
- Add formatNoExecutionError() for cases without execution context
- Update handleTriggerWebhookWorkflow to extract execution/workflow IDs from errors
- Modify getUserFriendlyErrorMessage to avoid generic SERVER_ERROR message
### Type Updates
- Add executionId and workflowId optional fields to McpToolResponse
- Add errorHandling optional field to ToolDocumentation.full
### Error Message Format
**With Execution ID:**
"Workflow {workflowId} execution {executionId} failed. Use n8n_get_execution({id: '{executionId}', mode: 'preview'}) to investigate the error."
**Without Execution ID:**
"Workflow failed to execute. Use n8n_list_executions to find recent executions, then n8n_get_execution with mode='preview' to investigate."
### Testing
- Add comprehensive tests in tests/unit/utils/n8n-errors.test.ts (20 tests)
- Add 10 new tests for handleTriggerWebhookWorkflow in handlers-n8n-manager.test.ts
- Update existing health check test to expect new error message format
- All tests passing (52 total tests)
### Documentation
- Update n8n-trigger-webhook-workflow tool documentation with errorHandling section
- Document why mode='preview' is recommended (fast, efficient, safe)
- Add example error responses and investigation workflow
## Why mode='preview'?
- Fast: <50ms response time
- Efficient: ~500 tokens (vs 50K+ for full mode)
- Safe: No timeout or token limit risks
- Informative: Shows structure, counts, and error details
## Breaking Changes
None - backward compatible improvement to error messages only.
