Manual testing of Nextcloud webhook_listeners app to validate webhook
payloads against ADR-010 expected schemas and document implementation
requirements for webhook-based vector synchronization.
## Changes
- Add test webhook endpoint at /webhooks/nextcloud in app.py
- Captures and logs webhook payloads for analysis
- Returns 200 OK immediately for webhook delivery confirmation
- Create webhook-testing-findings.md with comprehensive test results
- Captured payloads for 5/6 webhook event types
- Critical findings: missing node.id in deletions, type mismatches
- Implementation recommendations with code examples
- Update ADR-010 with Appendix A: Manual Webhook Testing Results
- Document actual vs expected webhook behavior
- Update event mapping table with tested webhook status
- Add 6 specific implementation recommendations
- Include testing implications for future development
## Testing Results
✅ NodeCreatedEvent - fires correctly, includes node.id (integer)
✅ NodeWrittenEvent - fires correctly, includes node.id (integer)
✅ NodeDeletedEvent - fires but missing node.id field (path only)
✅ CalendarObjectCreatedEvent - fires correctly with full iCal
✅ CalendarObjectUpdatedEvent - fires correctly with full iCal
❌ CalendarObjectDeletedEvent - does not fire (potential NC bug)
## Key Findings
1. NodeDeletedEvent missing node.id field - requires path-based fallback
2. node.id returns integer not string - needs casting for consistency
3. Multiple webhooks fire per operation - needs deduplication logic
4. Calendar deletion webhooks don't fire - reported as issue #53497
5. Calendar webhooks include full iCal content - enables rich parsing
## GitHub Issues
- Created issue #56371: NodeDeletedEvent missing node.id field
- Commented on issue #53497: CalendarObjectDeletedEvent not firing
Closes#283
