using-git-worktrees

Use when working on parallel branches simultaneously (multiple feature branches in flight; long-running experiments alongside production work; design-then-build cycles where the design branch outlives a single session). Examples: "I want to work on feature X while keeping main checked out for the bug fix", "set up a worktree for the v2 redesign", "experimental refactor I don't want polluting my main checkout", "this branch will run for weeks, give it its own dir". Native git worktree workflow per P3-C — no wrapper tool, just `git worktree add` with a documented `.worktrees/` subdirectory convention + `.gitignore` discipline. Refuses the "just stash and switch" rationalization when work-in-progress on the current branch makes branch-switching painful.
