Restore runtime deps: models, dots.tts, torchvision shadow

Rebuild the venv half of the reconstruction. Adds the two CPU onnx
detectors back under models/ (comic-text-detector, deepghs anime face,
both gitignored), re-clones the dots.tts checkout, and records both
recipes in requirements.txt so the next rebuild skips the archaeology.

Two pre-existing environment breakages had to be cleared:

- Arch's torchvision 0.25 is too old for torch 2.13, so every
  transformers model import died with "operator torchvision::nms does
  not exist". Shadowed with 0.28.0+rocm7.2 inside the venv only, so the
  system copy stays put.
- dots_tts refuses to import when torch and torchaudio minors differ,
  and that pair is unsatisfiable here: 2.11 is the newest torchaudio
  ROCm wheel there is. Verified 2.11 loads and resamples against 2.13,
  then scoped a bypass around the import in both call sites.

Self-checks 13/14. worker_layers still needs the ComfyUI workflow json,
which legacy/ took with it.
