Desktop: add a persistent setting to always open chat links in the system default browser

Feature request

Current behavior

In the Claude Code desktop app (macOS), clicking a URL in an assistant chat message opens a chooser (Open in app / Default browser), or opens the in-app Browser pane. Cmd+click opens the system browser directly.

Requested

A persistent preference (app setting or settings.json key) like "openLinksIn": "system" so that plain clicks on chat links always open in the OS default browser, without a per-link chooser.

Why

Users who live in their own browser (profiles, extensions, password manager, logged-in sessions) want every link in their default browser. The in-app Browser pane is great for the agent's verification work, but as a link target for the human it adds friction: the per-link chooser interrupts flow, and Cmd+click is easy to forget.

Environment

• Claude Code desktop app, macOS (Darwin 25.5.0)
• System default browser: Google Chrome (correctly set via LaunchServices)
