squash-tree v0.1.0

squash-tree is a Git extension that preserves, visualizes, and reverses squash commits by maintaining an explicit logical squash graph alongside Git’s native commit DAG. Git discards history during squash operations; squash-tree makes that history explicit, inspectable, and reversible using Git notes and refs — without modifying Git itself.

What’s in this release

• Show squash tree — git squash-tree <commit> prints the logical squash tree for a commit (e.g. git squash-tree HEAD).
• Init hooks — git squash-tree init (or init --global) installs Git hooks so squash metadata is recorded automatically on rebase, merge --squash, etc.
• Add metadata — git squash-tree add-metadata --root=<ref> --base=<ref> --children=<refs> to attach squash metadata to a commit manually.
• Spec & design — Formal Squash Tree spec and design doc in the repo.
