Initial commit: Polish AI dubbing pipeline (ComfyUI + Higgs Audio V3)

Converts SRT subtitles into a Polish lektor-style voiceover using a local
ComfyUI instance running Higgs Audio V3, then muxes the result back into the
source video as a second audio track. Video and original audio are always
stream-copied; only the new voiceover track is encoded.

Contents:
  lektor_ai_comfy.py    main pipeline (standard library only, needs ffmpeg)
  lektor_ai_comfy_v2.py batched-context experiment (timing unresolved)
  lektor_ai.py          earlier version using the hosted Boson AI API
  install_comfyui.sh    reproduces the ComfyUI environment, versions pinned
  docs/                 requirements, installation, usage, architecture,
                        troubleshooting
  gudowski/             voice references (.wav) with their transcripts (.txt)
