"title": "[P2] Implement real locking for Windows file token writes",
"body": "When ENTIRE_TOKEN_STORE=file is used on Windows, flockExclusive only opens the lock file and does not exclude another process. writeFileToken relies on this lock for its read-modify-write and also writes to a fixed path + \".tmp\" before renaming, so two concurrent logins or credential refreshes can overwrite each other's temp file, lose one credential, or return a rename error. Please use a real Windows interprocess lock, or otherwise make concurrent writes safe.",
