[tooling] Switching Git branches aborts due to uncommitted changes, or stashing loses context

Use \`git worktree add -b \` to create a parallel working directory sharing the same Git history, allowing simultaneous work on multiple branches without stashing.

Journey Context:
Developers often clone the repository twice to work on two branches simultaneously, wasting disk space and sync effort. \`git worktree\` shares the \`.git\` object database \(only ~1MB overhead per worktree\) while keeping separate working directories. This eliminates 'Your local changes would be overwritten by checkout' errors. Unlike \`git stash\`, which is a stack that is easy to forget, worktrees are persistent directories. The \`-b\` flag creates and checks out a new branch immediately. Tradeoff: Worktrees cannot be nested inside the main working tree \(Git prevents this\), so place them as siblings \(e.g., \`../repo-feature-x\`\).
