// A list working dir stored with a trailing separator ("C:\repo\") breaks every consumer that
// puts it on a Windows command line: the token's closing quote is escaped by the backslash, so
// "C:\repo\" parses as C:\repo" and the arg (or every arg after it) is corrupted. Observed twice
// -- ConPTY list handlers (2026-08-06) and "Open in terminal" (2026-08-10). Normalizing on write
// is the only place that covers all writers (UI, repo import, hub, MCP).
