Add keyboard shortcuts for agent permission confirmation dialogs

[trashhalo]

Currently, when an agent requests permission to use tools (like file edits), users must click buttons with the mouse to accept or reject. There's no dedicated keyboard shortcut to quickly approve these requests.

Current Behavior

• Permission dialogs show buttons: "Allow Once", "Allow Always", "Reject Once", "Reject Always"
• Users must use Tab to navigate to buttons and Enter to click them
• No direct keyboard shortcut exists (like Cmd+Y to accept)

Proposed Solution

Add keyboard shortcuts for agent permission dialogs:

• Cmd+Y (or similar) - Accept with "Allow Once"
• Cmd+Shift+Y - Accept with "Allow Always"
• Escape or Cmd+N - Reject

Use Case

This would significantly improve the workflow when working with agents, especially during rapid iteration where multiple permission checks occur. Having to reach for the mouse or tab through UI elements interrupts the coding flow.

Implementation Notes

Generated by claude code no idea if this is accurate.

The permission UI is rendered in crates/agent_ui/src/acp/thread_view.rs around lines 2425-2456. The buttons call authorize_tool_call with the appropriate option.

A new action like agent::AcceptToolCall could be added that automatically selects "Allow Once" when triggered via keyboard shortcut.

The issue is I am coming from Claude code in terminal so it's totally keyboard based. Making users engage their mouse on such a common, can be 100s of permissions checks in a day is pretty rough
