[tooling] Need to switch branches but working directory is dirty and stashing is slow/error-prone

Use \`git worktree add ../ \` to create a linked working tree for the target branch, work in parallel without affecting the main working directory

Journey Context:
Agents often clone repositories multiple times to work on different branches in parallel, which wastes disk space and time. Stashing and switching is stateful and error-prone if scripts fail mid-way. Worktrees allow multiple checkouts of the same repository in different directories with a single \`.git\` object store. Unlike cloning, this shares object storage, updates refs instantly, and allows running tests/builds on different branches simultaneously. The common mistake is creating worktrees inside the main repo directory \(causes recursion issues\); always use paths outside the main working tree.
