- SymPy 1.14.0 (bundled with Anaconda 2025.12) has a regression causing
  OverflowError in solve() for symbolic differentiation
- Bug occurs in solow.md when solving c.diff() due to factorint issue
  with large mpz integers trying to convert to float
- Pinning to 1.13.3 which works correctly with Python 3.13
- Added TODO to check for SymPy 1.14.1+ when available

SymPy Version Fix Applied

Added sympy==1.13.3 pinning to environment.yml to resolve execution failure in solow.md.

Issue: SymPy 1.14.0 (bundled with Anaconda 2025.12) has a regression causing OverflowError: 'mpz' too large to convert to float when executing solve(c.diff())[0] in the Solow growth model lecture.

Root Cause: Bug in sympy/ntheory/factor_.py where factorint fails to handle large multi-precision integers during symbolic differentiation.

Solution: Pin to SymPy 1.13.3 (from Anaconda 2025.06) which works correctly with Python 3.13.

TODO: Upgrade to SymPy 1.14.1+ when the fix is released.

Re-enabled the _build folder download step now that SymPy 1.13.3
pinning has been applied to fix the execution failure.
