feat: complete modular documentation system for all MCP tools (#60)

Browse Source 
- 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

returns: 'ValidationResult object containing isValid boolean, arrays of errors/warnings, and suggestions for fixes',
examples: [
'n8n_validate_workflow({id: "wf_abc123"}) - Validate with default settings',
'n8n_validate_workflow({id: "wf_abc123", options: {profile: "strict"}}) - Strict validation',
'n8n_validate_workflow({id: "wf_abc123", options: {validateExpressions: false}}) - Skip expression validation'
],
useCases: [
'Validating workflows before running them in production',
'Checking imported workflows for compatibility',
'Debugging workflow execution failures',
'Ensuring workflows follow best practices',
'Pre-deployment validation in CI/CD pipelines'
],
performance: 'Depends on workflow size and API latency. Typically 100-500ms for medium workflows.',
bestPractices: [
'Run validation before activating workflows in production',
'Use "runtime" profile for pre-execution checks',
'Use "strict" profile for code review and best practices',
'Fix errors before warnings - errors will likely cause execution failures',
'Pay attention to expression validation - syntax errors are common'
],
pitfalls: [
'Requires valid API credentials - check n8n_health_check first',
'Large workflows may take longer to validate',
'Some warnings may be intentional (e.g., optional parameters)',
'Profile affects validation time - strict is slower but more thorough',
'Expression validation may flag working but non-standard syntax'
