fix: correct version extraction and typeVersion validation for langchain nodes

Browse Source

This commit fixes two critical bugs affecting AI Agent and other langchain nodes:

1. Version Extraction Bug (node-parser.ts)
   - AI Agent was returning version "3" instead of "2.2" (the defaultVersion)
   - Root cause: extractVersion() checked non-existent instance.baseDescription.defaultVersion
   - Fix: Updated priority to check currentVersion first, then description.defaultVersion
   - Impact: All VersionedNodeType nodes now return correct version

2. typeVersion Validation Bypass (workflow-validator.ts)
   - Langchain nodes with invalid typeVersion passed validation (even typeVersion: 99999)
   - Root cause: langchain skip happened before typeVersion validation
   - Fix: Moved typeVersion validation before langchain parameter skip
   - Impact: Invalid typeVersion values now properly caught for all nodes

Also includes:
- Database rebuilt with corrected version data (536 nodes)
- Version bump: 2.17.3 → 2.17.4
- Comprehensive CHANGELOG entry
