-"""Export a scrubbed snapshot of the tool repo into a separate local git repo (fresh history).

-Usage: publish_snapshot.py [DEST] [--src REPO] [--ref REF] [--denylist FILE]
-
-- DEST (default ~/src/wf-public): created and `git init`ed on the first run.
-- The tree of REF (default master) is copied; inbox.md, .worktrees/, __pycache__/, out/ are dropped.
-- Denylist (default <src>/publish-denylist.local, git-ignored): one private word per line, `#` comments;
-  matched case-insensitively against every path and file content. Any match → nothing is written, exit 1.
-- First run → one commit 'initial public snapshot'; later runs → one commit whose message is the
-  CHANGES.md lines new since the last snapshot; no change → no commit.
-- Never pushes, never adds a remote: pushing is a manual step (docs/manual.md).
