* Optimize the WASI `random_get` implementation. Use `StdRng` instead of the `OsRng` in the default implementation of `random_get`. This uses a userspace CSPRNG, making `random_get` 3x faster in simple benchmarks. * Update cargo-vet audits for cap-std 0.25.3. * Update all cap-std packages to 0.25.3.
