Fixes the "PyBaMM main (non-blocking)" job, which fails on every branch, main included.

Cause

PyBaMM main is a uv workspace that also holds the solvers, packages/pybammsolvers, and their version is only bumped at a release: on main it is 0.11.1, the same as the release on PyPI, although the code has moved on. The job installed pybamm from main but took pybammsolvers from PyPI, to avoid compiling it. PyBaMM main now calls pybammsolvers.idaklu.shares_python_casadi, which no release has, so every test that builds a solver errors. No version constraint can catch this, as both report the same version.

Fix

Build both packages from PyBaMM main's source, as PyBaMM's own tests do:

• check out PyBaMM main with its submodules (SUNDIALS, SuiteSparse);
• install gfortran and libopenblas-dev, the packages PyBaMM's tests install;
• install pybammsolvers and pybamm from that checkout.

SUNDIALS and SuiteSparse take most of the build time. They are built into packages/pybammsolvers/.idaklu, which the solver module finds through an absolute RPATH, so that folder is cached with actions/cache, keyed on what it is built from: the submodule pins and install_KLU_Sundials.py. On a cache hit only the solver module is compiled. The job stays non-blocking.

To check

This could not be tested locally (no Fortran compiler or BLAS in the sandbox), so the first run of "PyBaMM main (non-blocking)" on this PR is the test; expect it to be slower while the cache is empty.

Pushed by the maintainer: changes under .github/workflows need the workflow scope.
