ROCm 7.2 + PyTorch 2.11.0 has a bug where PyTorch passes workspace=0 to
MIOpen convolutions, forcing fallback to the slow GemmFwdRest solver.
This caused s3gen.inference to take 15-22s instead of <5s, making
synthesis 3-4x slower than real-time audio playback.
ROCm 6.1 allocates workspace correctly so MIOpen picks fast GEMM solvers
without needing torch.compile workarounds.
Changes:
- Base image: rocm/dev-ubuntu-22.04:7.2 → 6.1
- torch 2.11.0 → 2.5.1 (rocm6.1 wheel index)
- Add pytorch_triton_rocm==3.1.0
- transformers 5.2.0 → 4.46.3, safetensors 0.5.3 → 0.4.0
- s3tokenizer unpinned → 0.3.0
- resemble-perth==1.0.1 directly (v1.0.1 is pip-installable; drop stub)
- Drop Dockerfile perth_stub steps
- Drop torch.compile and timing patches from engine.py (not needed)
- Drop multi-pass warmup from main.py (torch JIT warmup not needed)
- Drop ROCm 7.2-specific env vars from docker-compose.yml

resemble-perth uses uv-build which is incompatible with the old system
pip in the ROCm base image. Since watermarking is unnecessary for
self-hosted private use, stub out the perth module so chatterbox's
import is satisfied without any build complexity.

pip's isolated build environments don't have the uv binary available,
causing uv-build to fail. Installing with --no-build-isolation lets pip
use the already-installed uv from the system environment.

- Update transformers to 5.2.0 (required by official chatterbox)
- Add omegaconf (pulled by s3gen/flow.py)
- Install resemble-perth from git source
- Pin safetensors to 0.5.3
- Remove onnx (not a chatterbox dep)

resemble-perth, conformer, s3tokenizer, onnx, spacy-pkuseg, pykakasi,
and pyloudnorm are all chatterbox deps that were skipped by --no-deps
and need to be installed explicitly.

Wyoming-only server built around the official chatterbox TTS model.
Includes ROCm/AMD GPU support, sentence-level streaming, config.yaml
management, and Gitea CI for container builds.
