feat: implement Phase 2 validation improvements

Browse Source 
Phase 2 Professional Validation Features:

1. Validation Profiles:
   - minimal: Only required fields
   - runtime: Critical errors + security warnings
   - ai-friendly: Balanced (default)
   - strict: All checks + best practices

2. New Node Validators:
   - Webhook: Path validation, response modes, auth warnings
   - PostgreSQL: SQL injection detection, query safety
   - MySQL: Similar to Postgres with MySQL-specific checks

3. New Tools:
   - validate_node_minimal: Lightning-fast required field checking
   - Updated validate_node_operation with profile support

4. SQL Safety Features:
   - Detects template expressions vulnerable to injection
   - Warns about DELETE/UPDATE without WHERE
   - Catches dangerous operations (DROP, TRUNCATE)
   - Suggests parameterized queries

5. Enhanced Coverage:
   - Now supports 7+ major nodes with specific validators
   - Flexible validation based on use case
   - Professional-grade safety checks

This completes the major validation system overhaul from the original plan.
