czlonkowski 60ab66d64d feat: telemetry-driven quick wins to reduce AI agent validation errors by 30-40% ...

Enhanced tools documentation, duplicate ID errors, and AI Agent validator based on telemetry analysis of 593 validation errors across 3 categories:
- 378 errors: Duplicate node IDs (64%)
- 179 errors: AI Agent configuration (30%)
- 36 errors: Other validations (6%)

Quick Win #1: Enhanced tools documentation (src/mcp/tools-documentation.ts)
- Added prominent warnings to call get_node_essentials() FIRST before configuring nodes
- Emphasized 5KB vs 100KB+ size difference between essentials and full info
- Updated workflow patterns to prioritize essentials over get_node_info

Quick Win #2: Improved duplicate ID error messages (src/services/workflow-validator.ts)
- Added crypto import for UUID generation examples
- Enhanced error messages with node indices, names, and types
- Included crypto.randomUUID() example in error messages
- Helps AI agents understand EXACTLY which nodes conflict and how to fix

Quick Win #3: Added AI Agent node-specific validator (src/services/node-specific-validators.ts)
- Validates prompt configuration (promptType + text requirement)
- Checks maxIterations bounds (1-50 recommended)
- Suggests error handling (onError + retryOnFail)
- Warns about high iteration limits (cost/performance impact)
- Integrated into enhanced-config-validator.ts

Test Coverage:
- Added duplicate ID validation tests (workflow-validator.test.ts)
- Added AI Agent validator tests (node-specific-validators.test.ts:2312-2491)
- All new tests passing (3527 total passing)

Version: 2.22.12 → 2.22.13

Expected Impact: 30-40% reduction in AI agent validation errors

Technical Details:
- Telemetry analysis: 593 validation errors (Dec 2024 - Jan 2025)
- 100% error recovery rate maintained (validation working correctly)
- Root cause: Documentation/guidance gaps, not validation logic failures
- Solution: Proactive guidance at decision points

References:
- Telemetry analysis findings
- Issue #392 (helpful error messages pattern)
- Existing Slack validator pattern (node-specific-validators.ts:98-230)
