Fork tooling

strip.py

Makes an Enterprise-free snapshot of an upstream release. See the docstring and docs/spec/SPEC.md §2.2 for what it does and why.

git clone https://github.com/stalwartlabs/stalwart.git ~/src/stalwart-upstream   # outside this repo
git -C ~/src/stalwart-upstream fetch --tags
tools/fork/strip.py --upstream ~/src/stalwart-upstream --ref v0.16.22 --out /tmp/strip-v0.16.22

It writes OUT/tree (the stripped source) and OUT/STRIP-REPORT.md and .json. Exit 0 means verified clean. Exit 1 means malformed markers, or something Enterprise-only survived. Read the report's Problems section.

It needs Python 3.12+ (for tarfile's data filter) and git.
