fix: enhance node type format normalization for better AI agent compatibility (Issue #74)

Browse Source 
- Added support for n8n-nodes-langchain.* → nodes-langchain.* normalization
- Implemented case-insensitive node name matching (e.g., chattrigger → chatTrigger)
- Added smart camelCase detection for common patterns (trigger, request, sheets, etc.)
- Fixed get_node_documentation tool to use same normalization logic as other tools
- Updated all 7 node lookup locations to use normalized types for alternatives
- Enhanced getNodeTypeAlternatives() to normalize all generated alternatives

All MCP tools now consistently handle various format variations:
- nodes-langchain.chatTrigger (correct format)
- n8n-nodes-langchain.chatTrigger (package format)
- n8n-nodes-langchain.chattrigger (package + wrong case)
- nodes-langchain.chattrigger (wrong case only)
- @n8n/n8n-nodes-langchain.chatTrigger (full npm format)
