v1.67.1

Fixed

• IP-based geolocation no longer returns garbage results or logs parser warnings under concurrent requests: each worker thread now gets its own IP2Location database handle instead of sharing one non-thread-safe file cursor.
• Admins are no longer pinged on Discord when a guest account is created — the new-user notification now fires only for real user signups.
