fix(build): enforce Python 3.8+ and set manylinux2014 compatibility

This commit updates build configurations to ensure proper Python version
compatibility and Linux wheel building:

- Add Python version constraint (>=3.8) to pyo3 dependency
- Set manylinux2014 as explicit target for Linux builds
- Add --compatibility manylinux2014 flag to maturin build args

These changes prevent building for unsupported Python versions while
ensuring proper wheel compatibility across Linux distributions.
