Language selection not respected for mic transcription (Whisper) and summary

[ScreepCode]

Problem

The selected recognition language is ignored in two places:

1. Microphone transcription (Whisper)

WhisperEngine.transcribeChunk has the language hardcoded:

// WhisperEngine.swift
let langStr = strdup("en")
params.language = UnsafePointer(langStr)

No matter what language is selected in the UI (e.g. de-DE, fr-FR, ja-JP), Whisper always transcribes in the hardcoded language. Remote audio via SFSpeech works correctly because SFSpeechRecognizer is initialized with the correct locale — but the mic channel via Whisper does not.

2. Summary and Chat

SummaryService.buildPrompt and askQuestion have English-only prompts with no language instruction. The LLM always responds in English regardless of the meeting language.

Proposed Fix

Whisper:

• Add var language: String = "en" to WhisperEngine
• Use self.language in transcribeChunk instead of the hardcoded string
• Set whisperEngine.language in MeetingRecorder.startRecording() by extracting the 2-letter ISO code from recognitionLanguage (e.g. "de-DE" → "de")

Summary / Chat:

• Pass language: String to generateSummary and askQuestion
• Inject "Respond in German." (or the appropriate language) into the prompt
• Thread the language from recorder.recognitionLanguage (live view) and session.language (history view) through to SummaryService and ChatPanel
