feat: complete modular documentation system for all MCP tools (#60)
- Migrated all 40 MCP tools documentation to modular structure - Created comprehensive documentation with both essentials and full details - Organized tools by category: discovery, configuration, validation, templates, workflow_management, system, special - Fixed all TODO placeholders with informative, precise content - Each tool now has concise description, key tips, and full documentation - Improved documentation quality: 30-40% more concise while maintaining usefulness - Fixed TypeScript compilation issues and removed orphaned content - All tools accessible via tools_documentation MCP endpoint - Build successful with zero errors 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

- Validates n8n expression syntax in all fields
|

- Returns categorized issues with fix suggestions
|

|

The validation uses the same engine as validate_workflow but works with workflows already in n8n, making it perfect for validating existing workflows before execution.

Requires N8N_API_URL and N8N_API_KEY environment variables to be configured.`,
