fix(webview): address PR #8556 feedback (platform-aware key hints, i18n fixes, follow-up focus)

[hannesrudolph]

This PR supersedes #8556 to land the requested fixes because the original branch is on a fork and is not pushable from this environment.

Closes: #8555

Description

This PR introduces a new toggle in the settings under the "UI" section that allows users to switch between two input behaviors in the chat prompt editor:

• Enter = newline, Shift+Enter / Ctrl+Enter = send
• Enter = send, Shift+Enter = newline (current default)

The change is implemented by listening to the keydown event in the prompt input component and conditionally intercepting the Enter key based on the user’s preference, which is stored via VS Code’s configuration API.

This addresses user pain points around accidental submissions, ergonomic fatigue from holding Shift, and conflicts with input method workflows.

Test Procedure

• Send a message normally in the chat input
• Enable the feature
• Be happy that when you press enter, you receive a new line, and when you press ctrl+enter, the message is sent.
• Disable the feature
• Be happy that everything is back to default behavior.

Didn't send the message after pressing enter:

Did send it when pressing ctrl+enter

Documentation Updates

• This implementation does not introduce any new hardcoded keybindings beyond using standard modifier combinations (Shift+Enter, Ctrl+Enter), which are already common in chat interfaces.
• It would be ideal if there are documentation written to allow users to understand how to change the setting, but I think it is very intuitive
• I do not have time to write docs for this feature

The collapseThinking object is missing its description field, which breaks the JSON structure. This will cause i18n lookups to fail when users try to view this setting in Italian.
