Fix task restart to re-read updated tasks.json configuration

[Copilot]

When a task is running and the user edits tasks.json, clicking "Restart Task" on the warning dialog was restarting the task with the old definition instead of reading the updated configuration from tasks.json.

Problem

The _restart() method in abstractTaskService.ts was reusing the existing task object instead of re-reading from the workspace configuration:

private async _restart(task: Task): Promise<void> {
    // ... terminate task
    await this.run(task); // ← Uses old task definition
}

This meant that any changes made to tasks.json while a task was running would be ignored during restart.

Solution

Added a new _findUpdatedTaskByIdentifier() method that:

1. Uses the existing _findWorkspaceTasks() infrastructure to search current workspace configuration
2. Matches tasks by their definition identifier or label
3. Handles both custom tasks and configuring tasks (resolving them appropriately)
4. Falls back to the original task if no updated definition is found

The _restart() method now resolves the fresh task definition before running:

private async _restart(task: Task): Promise<void> {
    // ... terminate task
    const updatedTask = await this._findUpdatedTaskByIdentifier(task);
    await this.run(updatedTask || task); // ← Uses updated definition when available
}

Backward Compatibility

• If task resolution fails or no updated task is found, falls back to original behavior
• No breaking changes to existing API or functionality
• Uses existing VS Code task infrastructure patterns

Fixes #169267.

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:

• electronjs.org
  • Triggering command: node-gyp (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 my firewall allow list

this does not work, try reading #251755 which correctly re-reads tasks.json and watch for its update using await this._updateWorkspaceTasks(TaskRunSource.ConfigurationChange);

You're absolutely right. I've simplified the approach to use await this._updateWorkspaceTasks(TaskRunSource.ConfigurationChange); in the restart method as you suggested. This properly re-reads tasks.json configuration before restarting the task. The complex task matching logic has been removed in favor of this cleaner solution. Fixed in commit 597eb64.
