v0.9.1

Changed

• Consolidated download modules — download-stream.ts and download-hls.ts
  (which were 90% identical) merged into a single download.ts. The only difference
  (log message prefix) is now a parameterized label argument.
• Utilities centralized in utils.ts — findFfmpegPath and formatDuration
  moved from ffmpeg-utils.ts to utils.ts, making the utility module the single
  source of truth for pure helper functions.
• Removed getFfmpegPath() wrapper — the orchestrator (recorder/index.ts) now
  calls findFfmpegPath() directly instead of wrapping it in a one-liner that only
  added an error message.
• ffmpeg-utils.ts scoped to pipe-only — after extracting general utilities, the
  module now only exports the core pipeFfmpegSegment primitive and its associated
  constants. Cleaner separation of concerns.
• Removed no-op updateProgress from Display — the updateProgress() method
  was already a no-op (the recording timer is driven by an independent setInterval).
  Removed from the Display interface and the event subscription in index.ts. The
  download:progress event is still available in the recorder's event system for
  API consumers.
