* Studio: self-heal a pre-#6483-fix anyio>=4.14 stuck in existing installs

The <4.14 cap in constraints.txt/no-torch-runtime.txt only constrains new
anyio resolutions. An install made before that cap existed can already be
sitting on anyio 4.14+, and since it already satisfies mcp/fastmcp's
anyio>=4.5 floor, every later constrained install skips it as
already-satisfied -- so affected installs never recover and keep hitting
the cancel-scope RuntimeError on every request (#6797, a recurrence of
#6483). Force-reinstall anyio<4.14 whenever a stuck 4.14+ is detected.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Studio: also repair anyio on the update fast path

setup.sh's _SKIP_PYTHON_DEPS and setup.ps1's $SkipPythonDeps skip
install_python_stack.py entirely once the installed package version already
matches PyPI latest, so an install stuck on anyio>=4.14 with an otherwise
up-to-date package never reaches the repair added in install_python_stack.py.
Probe anyio on that fast path too and fall through to the full dependency
pass when it's still >=4.14, mirroring the existing ROCm/CPU-torch override
right below it.
