Steps to Reproduce:

1. Open a diff view in VS Code
2. Run the command git.diff.stageHunk (related code: https://github.com/microsoft/vscode/blob/0f58db74803c27f10770568b4bd8fec037bc2cdc/extensions/git/src/commands.ts#L1646C1-L1649C3)

Current Behavior:
The command doesn't stage anything when no selection is made.

Expected Behavior:
When running git.diff.stageHunk without a selection, it should automatically stage the hunk under the cursor.

Suggested Implementation:
The function this.diffStageHunkOrSelection(changes) could be enhanced with a default behavior to stage the hunk under the cursor when no selection is present. This would greatly improve the experience for keyboard-driven users. Also happened on #240935.

Benefits:

• Eliminates the need to manually select hunks before staging
• Provides intuitive behavior for cursor-based operations
• Improves workflow efficiency for keyboard users
