v0.7.26 — fix the v0.7.25 image build

v0.7.25 was tagged but never produced a Docker image — the build
failed in both amd64 and arm64 runtime stages with:

ERROR: Failed to build installable wheels for some pyproject.toml
based projects (llama-cpp-python)

Root cause

llama-cpp-python upstream doesn't publish a complete wheel matrix
to PyPI. They publish prebuilt CPU-only wheels to a dedicated index
at https://abetlen.github.io/llama-cpp-python/whl/cpu covering
every supported Python × linux_{x86_64,aarch64} combination.

pip in the python:3.12-slim runtime stage couldn't find a matching
manylinux wheel on PyPI and fell through to a source build,
which dies because slim images have no compiler / cmake / make.

The fix

One-line change in the runtime stage:

 COPY --from=python-build /wheels /wheels
-RUN pip install --no-cache-dir /wheels/*.whl \
+RUN pip install --no-cache-dir \
+        --extra-index-url https://abetlen.github.io/llama-cpp-python/whl/cpu \
+        /wheels/*.whl \
     && rm -rf /wheels

PyPI stays the primary index. The CPU wheel index is consulted
secondarily for packages PyPI doesn't fully cover — pip can only
pull llama-cpp-python from there because nothing else lives in
that index.

v0.7.25 status

The v0.7.25 GitHub Release page exists for documentation purposes,
but no :v0.7.25 Docker image was ever published. Use :v0.7.26
as the first release with the bundled-Qwen feature actually built.

Upgrade

docker pull ghcr.io/sanniheruwala/rednotebook-ai:v0.7.26

HF Space: bump the FROM tag in the Space's Dockerfile from
:v0.7.24 (the previous shipping release) directly to :v0.7.26.
Skip :v0.7.25 — it doesn't exist.
