Pull request overview

This PR addresses tool approval management UX by allowing combination-level approvals to carry a displayable arguments string, so users can distinguish and manage specific “tool + args” approvals (e.g., different extension.open invocations).

Changes:

• Changes the proposed approveCombination shape to include a { message, arguments? } object so tools can provide a user-visible argument summary.
• Persists the combination “arguments” string alongside the combination approval key and surfaces it in the Manage Tool Approvals quick tree via a “View Arguments” button/dialog.
• Updates Copilot’s VS Code command tool to populate the new approveCombination.arguments field and display args in the confirmation message.
