feat(amazonq): add keybinding shortcut for stop/reject/run shell commands (#7655)

## 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)

 ## Language Server Debugging

 If you want to connect a local version of language-servers to aws-toolkit-vscode, follow these steps:
 
 1. Clone https://github.com/aws/language-servers.git and set it up in the same workspace as this project by cmd+shift+p and "add folder to workspace" and selecting the language-servers folder that you just cloned. Your VS code folder structure should look like below.

 6. (Optional): Enable `"amazonq.trace.server": "on"` or `"amazonq.trace.server": "verbose"` in your VSCode settings to view detailed log messages sent to/from the language server. These log messages will show up in the "Amazon Q Language Server" output channel
 
 ### Breakpoints Work-Around
+
 If the breakpoints in your language-servers project remain greyed out and do not trigger when you run `Launch LSP with Debugging`, your debugger may be attaching to the language server before it has launched. You can follow the work-around below to avoid this problem. If anyone fixes this issue, please remove this section.
+
 1. Set your breakpoints and click `Launch LSP with Debugging`
 2. Once the debugging session has started, click `Launch LSP with Debugging` again, then `Cancel` on any pop-ups that appear
 3. On the debug panel, click `Attach to Language Server (amazonq)` next to the red stop button
 4. Click `Launch LSP with Debugging` again, then `Cancel` on any pop-ups that appear
 
 ## Language Server Runtimes Debugging

 If you want to connect a local version of language-server-runtimes to aws-toolkit-vscode, follow these steps:
