feat(amazonq): add keyboard shortcut for stop/reject/run commands (#7703)

## Problem

Currently, users need to manually click buttons or use the command
palette to execute common shell
commands (reject/run/stop) in the IDE. This creates friction in the
developer workflow, especially
for power users who prefer keyboard shortcuts.

## Solution

Reopen [Na's PR](#7178)
that added keyboard shortcuts for reject/run/stop shell commands

Update to align with new requirements.

Add VS Code feature flag (shortcut)

Only available if Q is focused
