fix: restore Python 3.13 support with proper system dependencies

- Add Python 3.13 back to CI workflows (test, lint, compile integration)
- Install OpenBLAS development libraries (libopenblas-dev, liblapack-dev, gfortran)
- Fix SciPy build issues by providing required BLAS dependencies
- Update migration documentation to reflect Python 3.10-3.13 support
- SciPy does support Python 3.13, issue was missing system libraries in CI

 **A:** Yes! There are no changes to how data is stored in Redis. All existing indices, caches, and chat histories will continue to work.

+### Q: When will Python 3.14 be supported?
 
-**A:** Python 3.13+ support will be added in a future release once our scientific dependencies (like `scipy`) add full support for these versions.
+**A:** Python 3.14 support will be added in a future release once our dependencies add support for Python 3.14.
 
 ### Q: Can I use langchain-redis v0.3.0 with langchain-core 0.3.x?
