Fix Azurite emulator to start all services (blob, queue, table) for durable functions support

[Copilot]

Fixes #4550

Previously, when debugging Azure Functions locally and the user selected "Run Emulator" to start Azurite, only the blob service was started. This caused durable functions to fail when they required queue or table services for orchestration and state management.

Changes Made

Updated the validateEmulatorIsRunning function in src/debug/validatePreDebug.ts to start all three Azurite services:

• Blob service (already working) - for general storage needs
• Queue service (newly added) - for durable function orchestration triggers and activities
• Table service (newly added) - for state persistence in certain durable function configurations

Code Changes

// Before: Only blob service started
await vscode.commands.executeCommand('azurite.start_blob');

// After: All three services started
await vscode.commands.executeCommand('azurite.start_blob');
await vscode.commands.executeCommand('azurite.start_queue');
await vscode.commands.executeCommand('azurite.start_table');

Impact

This ensures that durable functions work properly during local debugging without requiring manual intervention to start the missing queue and table services. The change is minimal (3 lines added) and maintains backward compatibility with existing functionality.

Testing

• ✅ Build passes without errors
• ✅ Linting passes without issues
• ✅ Maintains existing error handling and user experience
• ✅ No breaking changes to existing workflows

Warning

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• aka.ms
  • Triggering command: gulp preTest (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
