The recorded Repo field and the live lookup can name the same common git dir in different forms on Windows runners (8.3 short names from TEMP, case, separators), so === never matched and sessions were skipped. Add normalizeRepoPath plus sameRepoIdentity (device and inode fallback) in utils.js and use them for the repository identity comparison. Unit tests mock git output with Windows-shaped paths and cover the inode fallback via hard links on any OS.
