[BUG] Microphone dictation transcribes Portuguese speech as English text

What's Wrong?
When I click the microphone icon in the Claude Code chat input and speak in Portuguese, the transcription comes back as an unrelated English sentence — not a mistranslation, the content doesn't match what was said at all. This happens even though the Windows system locale/display language is correctly set to pt-BR.
What Should Happen?
The dictated text should be transcribed in Portuguese, matching what was spoken and the system's configured language.
Error Messages/Logs
Steps to Reproduce
- On a Windows machine with system language set to pt-BR, open the Claude Code panel in VS Code.
- Click the microphone icon in the chat input.
- Speak a sentence in Portuguese.
- The returned text is an unrelated English sentence, not a transcription of what was spoken.
Note: Checked claudeCode.* settings in the extension's package.json — there is no setting to control dictation/speech language (only preferredLocation, useTerminal, useCtrlEnterToSend, etc.).

Additional Information
VSCode extension version: 2.1.207
Windows 11 Home, build 10.0.26200
Windows locale confirmed as pt-BR via Get-WinUserLanguageList and Get-Culture.
Workaround in use: dictating via Windows native dictation (Win+H, which correctly respects pt-BR) and pasting text into the chat instead of using the built-in mic button.
