KiCad - the KiCad Bridge

"""Rebuild routing_deps/ (the vendored IPC client for the live routing verbs).

Downloads Windows x64 wheels for requirements-routing.txt, one tree per CPython
ABI the bridge may run under (start.bat picks system Python, else KiCad's), and
unpacks them under routing_deps/cp<maj><min>. The tree ships in the release zip
(tools/release_files.json "dirs") and is deliberately not pushed to the page repo.
