libhipblas.so.2 is required by libonnxruntime_providers_rocm.so but was
missing from the base image install.

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

The named volume overlay was causing SQLite 'unable to open database file'
crashes. MIOpen's default cache location (~/.config/miopen) works reliably
inside the container. The startup warmup repopulates it each run.

MIOpen crashes with SQLite 'unable to open database file' when the
directory doesn't exist at container start. mkdir + chmod 777 ensures
the path is present and writable before the named volume overlays it.

Using :latest was pulling a ROCm 6.x image whose MIOpen was incompatible
with our ROCm 7.2 PyTorch wheels. Pinning to the 7.2 tag gives matching
MIOpen libraries and should resolve the workspace/fallback performance issue.

- CI: cache-from/cache-to with mode=max stores all intermediate layers
in the registry so subsequent builds skip unchanged layers (especially
the slow ROCm PyTorch download)
- Dockerfile: move COPY perth_stub.py below pip install layers so a
stub change doesn't bust the cache for everything above it

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.

pip's isolated build environments inherit system PATH but don't get
the uv binary automatically. Symlinking via uv.find_uv_bin() makes it
available so resemble-perth's uv-build backend can execute.

resemble-perth uses uv as its build backend; without uv installed
the metadata-generation step fails.
