feat: add "Ask @azure" context menu action for AKS clusters (#2183)

[Tatsinnit]

Add "Ask @Azure" context menu action for AKS clusters

Fixes #2183

Summary

Adds a new "Ask @Azure" context menu item to AKS clusters in the Cloud Explorer tree view. When clicked, it opens GitHub Copilot Chat with a pre-populated query containing the cluster name and ARM resource ID, targeting the @azure chat participant.

Changes

• New command aks.askAzureCopilot — resolves the selected cluster node and opens Copilot Chat via workbench.action.chat.open
• Menu visibility — item only appears when github.copilot-chat.activated is true
• Tree item ID fix — uses ARM resource ID (clusterResource.id) instead of name + resourceGroup for consistency

Files Changed

File	Change
package.json	Command + menu contribution registration
package.nls.json	Localization string
extension.ts	Command registration
aksAskAzureCopilot.ts	Command implementation (new)
aksClusterTreeItem.ts	Tree item ID fix

Testing

1. Install the extension with GitHub Copilot Chat active
2. Right-click an AKS cluster in Cloud Explorer
3. Verify "Ask @Azure" appears in the context menu
4. Click it — Copilot Chat opens with: @azure I'd like to talk about my <cluster-name> Azure Kubernetes Service cluster (resource ID: <arm-id>).

❤️ 💡Gentle fyi and hunch: This needs reference check here, @tejhan could be the best one as we want to avoid and reciprocal effect. Thanks

Pull request overview

Adds a new "Ask @Azure" context menu entry on AKS cluster nodes in the Cloud Explorer that opens GitHub Copilot Chat pre-populated with a query targeting the @azure participant and including the cluster name and ARM resource ID. Also switches the AKS cluster tree item id from name + resourceGroup to the ARM resource ID for consistency.

Changes:

• New aks.askAzureCopilot command implementation, registration, and context-menu contribution (gated by github.copilot-chat.activated).
• Localization entry for "Ask @Azure".
• AksClusterTreeItem.id now uses clusterResource.id (ARM resource ID).
