v1.3.2

A patch release fixing two visible bugs — wildly inaccurate progress/ETA and wrong output file extensions — plus a faster job start.

Fixed

• Progress and ETA were 1000× off. ffmpeg reports encode position in
  microseconds (under a misleadingly-named out_time_ms key); it was read as
  milliseconds. Now normalized correctly, so the progress bar and time-remaining
  are accurate.
• Output files now use the right extension. Each template declares the
  container it actually encodes, so "to WebM" produces .webm, "to MOV" .mov,
  audio extracts .mp3/.wav, GIF .gif, etc. — instead of everything being
  written as .mp4. (Stream-copy templates — strip audio/video, trim — still
  keep .mp4 to preserve prior behavior.)

Changed

• Internal cleanups: settings are loaded once at startup so get_settings is a
  pure read, and IPC calls were consolidated behind service wrappers — no
  user-facing behavior change.
