Consistent Enqueue shortcut to match VS Code Copilot's Alt + Enter #2624

Describe the feature or problem you'd like to solve

Two different shortcuts to remember for VS Code Copilot and Github Copilot

Proposed solution

• Either make enqueue the default behaviour
• OR, give a quick menu selector to Send immediately, Enqueue or Steer
• OR, allow configurability (I don't want to change my VS Code shortcuts)
