Subject: [PATCH 06/21] ci: upgrade Python from 3.8 to 3.10+ in CI workflows
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Python 3.8 reached EOL in October 2024. Newer package versions
(scikit-learn>=1.8, scikit-image>=0.26, tensorboard>=2.20) no longer
support Python 3.8, causing dependabot PRs to fail CI.

- functional-test: 3.8 → 3.10
- code-lint: 3.8 → 3.10
- smoke-test: 3.8/3.9/3.10 → 3.9/3.10/3.11

Subject: [PATCH 12/21] fix: compat shim for IAAAdditiveGaussianNoise in
 albumentations>=1.4

Instead of downgrading albumentations, use try/except to fall back
to GaussNoise when IAAAdditiveGaussianNoise is removed.

 implementation

pnnx==20251031 removed the wrapper submodule.
convert_inputshape_to_cmd is simply converting tensor shape
to a pnnx CLI argument; inlined it directly.

The removed variables (expand_kernel, expand_stride, num_elements)
and unused imports in MobileNetv4 are intentional or tied to
commented-out code. Instead of modifying production model code,
ignore these specific lint issues via pyproject.toml.
