[tooling] Need to work on multiple Git branches simultaneously without stashing, cloning the repo multiple times, or losing context

Use \`git worktree add ../ \` to create a linked working tree. This creates a new directory with the specified branch checked out while sharing the same underlying Git object database \(\`.git\` is a file pointing back to the main repo\). Switch contexts instantly by changing directories. Remove with \`git worktree remove \` to clean up the directory and unlink the ref.

Journey Context:
Developers facing parallel work \(e.g., hotfix vs. feature\) often resort to \`git stash\` \(risky, easy to forget\) or full repository clones \(wastes disk space and network time, diverges easily\). Worktrees have been native since Git 2.5\+ but are underused because they break the mental model of 'one repo = one directory.' The critical insight is that worktrees share the object database, meaning \`git log\`, \`git diff\`, and object lookups are instant and consistent across all worktrees. Unlike separate clones, you cannot accidentally commit to the wrong branch from the wrong directory because each worktree is locked to its branch until removed. Common mistake: creating a worktree inside the main repository directory \(this causes confusing nesting; always use a sibling directory like \`../repo-branch\`\). Also, remember that uncommitted changes in one worktree do not appear in others, which prevents the 'dirty state' confusion that \`git stash\` often causes but requires committing or stashing within the specific worktree.
