feat: Update skills for n8n-mcp unified tool API (v1.1.0)

BREAKING: Updated all skills to reflect n8n-mcp tool consolidation:

## Tool API Changes
- get_node_essentials → get_node({detail: "standard"})
- get_node_info → get_node({detail: "full"})
- get_node_documentation → get_node({mode: "docs"})
- search_node_properties → get_node({mode: "search_properties"})
- validate_node_minimal → validate_node({mode: "minimal"})
- validate_node_operation → validate_node({mode: "full"})
- get_property_dependencies → REMOVED (use get_node modes)

## New Features Documented
- Workflow activation via API (activateWorkflow/deactivateWorkflow operations)
- n8n_deploy_template - deploy templates directly to n8n
- n8n_workflow_versions - version history and rollback
- n8n_test_workflow - trigger execution
- n8n_executions - manage executions
- Smart parameters (branch, case) for IF/Switch connections
- Intent parameter for better AI responses

## Documentation Updates
- Added YouTube video introduction with thumbnail
- Added GitHub stars badge (1.2k milestone)
- Added build.sh script for dist packaging
- Fixed "5 skills" → "7 skills" inconsistency in README

## Files Updated
- n8n-mcp-tools-expert: Complete rewrite of SKILL.md, SEARCH_GUIDE.md,
  VALIDATION_GUIDE.md, WORKFLOW_GUIDE.md
- n8n-node-configuration: Updated SKILL.md, DEPENDENCIES.md
- n8n-validation-expert: Updated SKILL.md, ERROR_CATALOG.md, FALSE_POSITIVES.md
