refactor: rewrite all MCP tool documentation for AI agent optimization
- Redesigned documentation to be utilitarian and AI-agent focused - Removed all pleasantries, emojis, and conversational language - Added concrete numbers throughout (528 nodes, 108 triggers, 264 AI tools) - Updated all tool descriptions with practical, actionable information - Enhanced examples with actual return structures and usage patterns - Made Code node guides prominently featured in overview - Verified documentation accuracy through extensive testing - Standardized format across all 30+ tool documentation files Documentation now optimized for token efficiency while maintaining clarity and completeness for AI agent consumption. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
