[BUG][A11y] Desktop (Windows): new replies in the Code tab are not announced by NVDA

What's Wrong?

In the Claude desktop app for Windows, Code tab, NVDA does not announce a new reply, neither while it streams nor when it is finished. The reply is only read if I move the mouse pointer over the reply area (NVDA mouse tracking); keyboard-only, nothing is spoken. NVDA's "Report dynamic content changes" option is enabled.

I could not determine whether the reply area of the Code tab is exposed as an aria-live region. Issue #83167 says the regular chat view of Claude Desktop has one; if the Code tab has one too, it does not reach NVDA here.

What Should Happen?

When a reply is complete, NVDA announces it automatically, for example through an aria-live="polite" region updated once at completion (not token by token). Alternatively, offer a screen reader mode in the desktop app like the CLI's --ax-screen-reader.

Steps to Reproduce

1. Start NVDA (2026.2) on Windows 11.
2. Open the Claude desktop app, Code tab.
3. Send any message and wait for the reply.
4. NVDA stays silent until the mouse pointer is moved over the reply area.

Additional Information

Environment: Claude desktop app 2.2553.1.0 (Windows package), NVDA 2026.2, Windows 11 Pro Insider Preview 10.0.26220. The bundled Claude Code version is not shown to me.
Related: #83167 (message list, Claude Desktop), #94353 (Code tab slash menu silent with NVDA), #90761 (keyboard operability tracking).
Workaround I use: a Stop hook that reads last_assistant_message aloud with Windows speech (System.Speech).
