Setting to disable terminal quick fixes

[Copilot]

Implementation Summary

• Add new setting terminal.integrated.shellIntegration.quickFixEnabled to the terminal configuration
  • Add to TerminalSettingId enum in /src/vs/platform/terminal/common/terminal.ts
  • Add configuration schema in /src/vs/workbench/contrib/terminal/common/terminalConfiguration.ts
• Update quick fix addon to check the setting before registering decorations
  • Modify _registerQuickFixDecoration in /src/vs/workbench/contrib/terminalContrib/quickFix/browser/quickFixAddon.ts
  • Add configuration change listener to update behavior dynamically
• Build and test the changes - compilation successful with 0 errors
• Write tests for the new setting
• Complete implementation and documentation

Solution Overview

Added a new boolean setting terminal.integrated.shellIntegration.quickFixEnabled (default: true) that allows users to disable quick fix decorations in the terminal. This addresses the issue where users find the AI sparkle icon and lightbulb icons distracting when commands fail.

Key Features

1. User Control: Users can now disable quick fix icons via settings
2. Clean Integration: Setting is logically grouped with other shell integration settings
3. Dynamic Updates: Changes take effect immediately without restarting terminals
4. Backward Compatible: Default value maintains current behavior
5. Complete Coverage: Hides both lightbulb and AI sparkle icons

Usage

To disable quick fix icons:

1. Open Settings (Ctrl+, or Cmd+,)
2. Search for terminal.integrated.shellIntegration.quickFixEnabled
3. Uncheck the setting

Or add to settings.json:

{
  "terminal.integrated.shellIntegration.quickFixEnabled": false
}

Technical Implementation

• Setting check added before decoration registration in _registerQuickFixDecoration()
• Configuration listener clears existing decorations when setting changes
• Quick fixes are still generated internally but visual decorations are not shown
• Tests verify behavior with setting enabled and disabled

<issue_title>GitHub Copilot ability to turn of AI sparkle icon in terminal.</issue_title>
<issue_description>With GitHub Copilot enabled, I keep seeing a distracting AI sparkle icon appear in the terminal. When I click it it gives me "Quick Fix" options. But there's nothing to "fix". I'm just running commands in the terminal, and I don't need little sparkles appearing.

I can't seem to disable this sparkle icon from appearing in the terminal. I asked in GitHub Copilot itself, and the suggestions it gave were for settings that either didn't exist or were irrelevant. Here are a few of its suggestions:

• terminal.integrated.suggest.enabled
• github.copilot.terminal.suggestEnabled
• github.copilot.chat.terminalChatLocation
• github.copilot.editor.enableCodeActions
• terminal.integrated.quickFix.enabled
• terminal.integrated.enableCommandActions

I finally realized the LLM was just guessing and that there is probably no setting to do this.

Please provide a way just to keep the AI sparkle icon from appearing in the terminal. Thanks.</issue_description>

Comments on the Issue (you are @copilot in this section)

@Tyriar @garretwilson it only shows when the command fails doesn't it?

It's not distracting at all personally.

I think we should have a setting like terminal.integrated.shellIntegration.decorationsEnabled to hide quick fixes in general though (including the lightbulb).</comment_new>
