This commit adds automatic detection of n8n server version and filters
workflow settings properties based on what the target version supports.
Changes:
- Add n8n-version.ts service for version detection via /rest/settings
- Fix nested response structure handling (data.data.versionCli)
- Add N8nVersionInfo and N8nSettingsData types
- Update N8nApiClient with getVersion() and version-aware filtering
- Clean workflow settings before API update based on detected version
Version compatibility:
- n8n < 1.37.0: 7 core properties only
- n8n 1.37.0+: adds executionOrder
- n8n 1.119.0+: adds callerPolicy, callerIds, timeSavedPerExecution, availableInMCP
Fixes#466
