Brian 73601bb13d packaging: stop exact-pinning build backends

Exact setuptools/wheel pins block platform-specific backend patches and
make isolated pip installs fail on Android/Termux Python. Keep a setuptools
lower bound only, drop the unused wheel backend pin, keep requirements.txt
aligned with core package deps, and install the Spaces extra in Docker
instead of pulling bitsandbytes by default.

Android/Termux is still not a supported runtime; the new platform note
documents host wheels, ANDROID_API_LEVEL, and --no-build-isolation so
pip does not isolate a second setuptools or compile manylinux-only
extensions.

Android / Termux install notes

Android is not a supported OBLITERATUS runtime. These notes exist so a Termux (or other Android Python) install does not fight host wheels or download a second setuptools behind PEP 517 isolation.

sys.platform on current Android CPython is android, not linux. The locked CPU PyTorch index in pyproject.toml is intentionally limited to linux and win32 manylinux/Windows wheels. Do not point Android at that index.

Layout

Install the platform's own python, setuptools, and scientific wheels first (torch, numpy, and whatever Termux already packages). Those builds carry the Android patches that PyPI wheels do not. safetensors and tokenizers are Rust extensions; rustup does not host aarch64-linux-android, so install Termux rust before pip and export the API level Python was built against (24 on current Termux):
```
pkg install rust
export ANDROID_API_LEVEL=24
```
Isolated pip builds of meson packages (pandas, matplotlib) will try to compile cmake/ninja from source and can hang under proot. Install those binaries from Termux first (pkg install ninja cmake python-matplotlib python-scipy python-pillow python-psutil python-pyarrow python-greenlet python-brotli python-cryptography python-rpds-py python-msgpack libraqm harfbuzz). PyPI psutil sdists reject sys.platform == "android"; the Termux package is patched. Termux matplotlib needs libraqm. PyPI tokenizers abi3 wheels fail on CPython 3.14 (PyBaseObject_Type); rebuild without the abi3 cargo feature so the extension is cp314 instead of abi3. Then install OBLITERATUS without build isolation:
```
python -m pip install --no-build-isolation -e ".[spaces]"
```

If pip still tries to compile torch or numpy from source, install the project over the host packages instead:

python -m pip install --no-build-isolation --no-deps -e .
python -m pip install --no-build-isolation "gradio>=6.7,<7.0"

Do not use uv sync --locked on Android. The lock resolves Linux/Windows CPU PyTorch and does not contain android_* wheels for torch, numpy, pyarrow, tokenizers, or bitsandbytes.

The quantization and qwen-hybrid extras are CUDA-oriented and are not an Android install path.
