Description

Ctrl+Backspace. This shortcut is captured globally within the chat input field, which conflicts with the standard OS/editor behavior of Ctrl+Backspace deleting the word to the left of the cursor.

Expected behavior:
Ctrl+Backspace should only trigger Stop when the input field is not focused, or ideally shouldn't hijack a standard text-editing shortcut at all — similar to how #10647 flagged that Ctrl+Shift+Backspace ("Reject Diff") shouldn't override IntelliJ's native shortcut when there's no diff to reject. In this case, Stop should not override basic word-delete in the input box, especially since the two actions have no relationship to each other from the user's perspective.

Workaround: none currently — there doesn't appear to be a config.yaml or keybinding entry to remove/rebind this, since it isn't registered as a normal VS Code keybinding but instead handled inside the webview itself.

To reproduce

Steps to reproduce:

1. Open the Continue chat panel and send a message so a response starts streaming.
2. While the response is still streaming, click into the chat input box and try to use Ctrl+Backspace to delete a word you've typed.
3. Instead of deleting a word, it triggers the Stop action.
