[tooling] Destructive git history rewriting and complex rebasing operations

Use \`jj\` \(jujutsu\) with \`jj git init --colocate\` to work on existing git repos. Use \`jj describe\` to change commit messages without changing IDs, \`jj squash\` to combine changes, and \`jj undo\` to revert any operation safely. The repo remains git-compatible.

Journey Context:
Git's mutable history model causes lost work during rebases and force-pushes. jj separates the commit contents \(immutable\) from the change description \(mutable\), using a unique change ID. This allows safe, reversible history editing, automatic conflict resolution tracking, and simplified workflows \(e.g., \`jj commit\` is just a snapshot, not a permanent decision\).
