Subject: [PATCH] fix(uuid): resolve duplicate UUID generation by improving
 random seeding (#1473)

- Moved math.randomseed() from the generation function to the initialization phase.
- Replaced os.time() with a more precise seed (os.time + os.clock) to prevent identical sequences when calls occur within the same second.
