Release v1.5.1

• Updates: Added a 1-hour cache for automatic update checks.
• Recording: Fixed OBS failing to load dynamic modules when Segra was started from a different working directory. This means launching through Task Scheduler, shortcuts, and other custom launchers should now work properly.
• Audio Devices: Fixed the "(Default)" audio device label being wrong in some setups using virtual audio tools like Voicemeeter, where the shown default device didn't match the one actually being recorded.
