[tooling] Switching branches destroys in-progress work or requires messy stashes

Use \`git worktree add ../repo-feature-name feature-branch\` to check out a branch to a sibling directory; work on multiple branches simultaneously without stashing or cloning the repository again.

Journey Context:
Developers often stash incomplete work to review a PR on another branch, or clone the repository multiple times to work in parallel, wasting disk space and sync effort. Worktrees use the same underlying Git object database \(\`.git\` is shared via \`gitdir\` links\), so creating a new worktree is instant and consumes no extra space for history. Unlike cloning, changes committed in one worktree are immediately available in others because they share the same object store. This eliminates the 'stash pop' dance and prevents accidental loss of staged changes when switching contexts.
