Chore: Remove Scripts and use only polyglot commands

[kaifcoder]

Replace Custom dev-basic.cjs Script with npx create-polyglot Commands

📝 Description

Remove the custom dev-basic.cjs file and replace its functionality with standardized npx create-polyglot commands to eliminate redundancy and ensure consistency across the polyglot project.

🎯 Current State

• Custom script at dev-basic.cjs (200+ lines) handles:
  • Service discovery and startup
  • Package manager detection
  • Admin dashboard launching
  • Process management and logging
  • Signal handling for graceful shutdown

📋 Tasks

• Remove dev-basic.cjs file
• Update root package.json to use npx create-polyglot dev exclusively
• Verify create-polyglot provides equivalent functionality:
  • Multi-service startup
  • Admin dashboard on port 9000
  • Process orchestration
  • Logging capabilities
• Test that npm run dev works identically after migration

✅ Benefits

• Reduced maintenance: Remove 200+ lines of custom code
• Consistency: Use official create-polyglot tooling
• Reliability: Leverage tested, maintained solution
• Simplicity: Single command replaces complex custom logic
