Development record

docs/how-to/upgrade-to-v0.13.0.md:45-47 says abcd ahoy names any worktree the repair left unlinked. The check is raised only inside a git repository (internal/core/ahoy/detect.go:111-119 gates detectStoreWorktrees on the folder kind, though its gap is scope machine, store_worktrees.go:128), so abcd ahoy run in the same plain Terminal window, typically the home folder, reports nothing about worktrees.
