fix: recognize all trigger node types including executeWorkflowTrigger (#351) (#352)

Browse Source

This fix addresses issue #351 where Execute Workflow Trigger and other
trigger nodes were incorrectly treated as regular nodes, causing
"disconnected node" errors during partial workflow updates.

## Changes

**1. Created Shared Trigger Detection Utilities**
- src/utils/node-type-utils.ts:
  - isTriggerNode(): Recognizes ALL trigger types using flexible pattern matching
  - isActivatableTrigger(): Returns false for executeWorkflowTrigger (not activatable)
  - getTriggerTypeDescription(): Human-readable trigger descriptions

**2. Updated Workflow Validation**
- src/services/n8n-validation.ts:
  - Replaced hardcoded webhookTypes Set with isTriggerNode() function
  - Added validation preventing activation of workflows with only executeWorkflowTrigger
  - Now recognizes 200+ trigger types across n8n packages

**3. Updated Workflow Validator**
- src/services/workflow-validator.ts:
  - Replaced inline trigger detection with shared isTriggerNode() function
  - Ensures consistency across all validation code paths

**4. Comprehensive Tests**
- tests/unit/utils/node-type-utils.test.ts:
  - Added 30+ tests for trigger detection functions
  - Validates all trigger types are recognized correctly
  - Confirms executeWorkflowTrigger is trigger but not activatable

## Impact

Before:
- Execute Workflow Trigger flagged as disconnected node
- Schedule/email/polling triggers also rejected
- Users forced to keep unnecessary webhook triggers

After:
- ALL trigger types recognized (executeWorkflowTrigger, scheduleTrigger, etc.)
- No disconnected node errors for triggers
- Clear error when activating workflow with only executeWorkflowTrigger
- Future-proof (new triggers automatically supported)

## Testing

- Build: ✅ Passes
- Typecheck: ✅ Passes
- Unit tests: ✅ All pass
- Validation test: ✅ Trigger detection working correctly
