* fix(cli): use 'where' instead of 'which' on Windows for FFmpeg and browser detection - findFFmpeg() now uses 'where ffmpeg' on Windows, 'which ffmpeg' on Unix - whichBinary() now uses 'where' on Windows, 'which' on Unix Fixes FFmpeg detection failure on Windows where 'which' command doesn't exist. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(cli): handle multi-line output from Windows 'where' command Windows 'where' can return multiple paths (one per line) when there are multiple matches on PATH. Take only the first non-empty line. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(cli): extend Windows 'where' fix to whisper, tts, and clipboard modules - whisper/manager.ts: whichBinary() now uses 'where' on Windows - tts/synthesize.ts: findPython() now uses 'where' on Windows - utils/clipboard.ts: detectProvider() now uses 'where' on Windows All functions handle multi-line output from 'where' command.
