UUID: NewV7() always generates a UUID with 7000 on browsers (Golang)

A bug has been discovered in Go 1.27's `uuid.NewV7()` function when compiled for JavaScript/WebAssembly targets: the function consistently generates UUIDs with "7000" in a fixed position instead of random bytes. The expected behavior is for all portions of the UUID to include random data, but on browsers the third section always shows "7000" (e.g., `019ee60f-29b3-7000-a12b-f817e25db8f4`).
