feat: Refactor service management scripts to use a unified dev script

- Added package.json to manage development scripts.
- Updated restart-services.ps1 to call the new dev script for starting services.
- Refactored start-admin.ps1, start-backend.ps1, start-frontend.ps1, and start-mcp.ps1 to utilize the dev script for starting respective services.
- Enhanced stop-services.ps1 to improve process termination logic by matching command patterns.

 ## Run
 
-### Monorepo scripts
+### Recommended
 
 From the repository root:
 
+```powershell
+npm run dev
+```
+
+This starts `frontend + admin + backend` in a single Windows Terminal window with multiple tabs.
+
+Common shortcuts:
+
+```powershell
+npm run dev:mcp
+npm run dev:frontend
+npm run dev:admin
+npm run dev:backend
+npm run dev:mcp-only
+npm run stop
+npm run restart
+```
+
+### PowerShell entrypoint
+
+If you prefer direct scripts, use the single root entrypoint:
+
 ```powershell
 .\dev.ps1
-```

-Frontend + backend + MCP:
-
-```powershell
 .\dev.ps1 -WithMcp
+.\dev.ps1 -Only frontend
+.\dev.ps1 -Only admin
+.\dev.ps1 -Only backend
+.\dev.ps1 -Only mcp
 ```
 
-Only frontend:

 ```powershell
