- Add nanvix/cpython and nanvix/cymem as git submodules (deps/) - Rewrite z script: setup downloads Nanvix runtime + inits submodules + fetches CPython build deps; new 'build' command cross-compiles cymem and CPython from source with cymem.cymem as a built-in static module - Add patches/cymem_builtin.c shim to bridge makesetup's init function naming (PyInit_cymem_cymem) with cymem's actual export (PyInit_cymem) - Register cymem.cymem via Modules/Setup.local during CPython build - Remove pre-built CPython/cymem artifact downloads from z script - Update CI workflow: checkout with submodules, add build step, remove get-release-info job and CPYTHON_TAG/CYMEM_TAG variables - Add cymem to site-packages-extra.txt (pure Python package files) - Add functional test test_101_cymem.py (from cymem.cymem import Pool)

This pull request introduces major changes to the build and CI workflow, switching from downloading pre-built CPython artifacts to building CPython and the
cymemmodule from source as submodules. It adds support for linkingcymemas a built-in CPython module, updates the CI pipeline to reflect this new approach, and provides new scripts and tests to ensure proper integration. The most important changes are grouped below.
