feat: Add "Restart Rslint Server" command to VSCode extension

[Copilot]

This PR implements a "Restart Rslint Server" command for the VSCode extension that allows users to restart the Rslint language server without restarting the entire VSCode window.

Problem

When users modify rslint.jsonc configuration files, they currently need to restart the entire VSCode window for the changes to take effect. This is inconvenient and disrupts the development workflow.

Solution

Added a restart command that:

• Stops and restarts all Rslint instances across workspace folders
• Provides user feedback with success/error notifications
• Integrates with Command Palette for easy access via Ctrl+Shift+P → "Restart Rslint Server"
• Works through Rslint menu for quick access
• Handles errors gracefully with proper logging and user notifications

Usage

Users can now restart the Rslint server in two ways:

1. Command Palette: Press Ctrl+Shift+P (or Cmd+Shift+P) and type "Restart Rslint Server"
2. Rslint Menu: Use existing Rslint commands menu to access the restart option

Implementation Details

• Extension.ts: Added restartAllInstances() method that coordinates stopping and starting all Rslint instances
• commands.ts: Uncommented existing restart command scaffolding and implemented proper error handling
• package.json: Added command contribution for Command Palette integration

The implementation leverages existing infrastructure and follows VSCode extension patterns, making it a minimal but effective solution.

Fixes #299.

@copilot fix ci

Fixed CI by initializing the typescript-go submodule that was required for the Go build process. The CI workflow already includes submodules: true in the checkout steps, so the build should now pass successfully. The issue was that the typescript-go dependency wasn't available, causing the Go build to fail with "no such file or directory" error.

Firewall rules blocked me from connecting to one or more addresses (expand for details)

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

• update.code.visualstudio.com
  • Triggering command: node .vscode-test-out/runTest.js (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)
