- Fix SpeechTranscriber initialization for macOS 26 release (use transcriptionOptions/reportingOptions/attributeOptions instead of preset) - Add --custom-phrases CLI argument for custom vocabulary boosting - Use AnalysisContext.contextualStrings with vocabulary tag - Use file-based SpeechAnalyzer initializer Reference: https://developer.apple.com/documentation/speech/analysiscontext
- contextualStrings only works with SFSpeechRecognizer + server-based recognition - SpeechTranscriber (macOS 26) ignores contextualStrings - Auto-switch to SFSpeechRecognizer when --custom-phrases is provided - Add --server flag to force server-based recognition - Add --debug flag for troubleshooting

This PR:
--sfspeechflag to explicitly useSFSpeechRecognizer. The default behavior remains using SpeechAnalyzer.--custom-phrasesCLI option for adding custom vocabulary support. When this option is used, the CLI automatically switches toSFSpeechRecognizer, sinceSpeechAnalyzerdoes not support custom vocab.live modefrom SpeechTranscriber to resolve build failure.
