サンプル
In rand 0.9+, thread_rng() and .gen()/.gen_range() are replaced by rand::rng() and .random()/.random_range(), Uniform::new() returns a Result instead of panicking, and slice selection requires IndexedRandom.

コントラクト
- rand::rng() initializes the thread-local generator instead of deprecated rand::thread_rng()
- rng.random() and rng.random_range() replace removed .gen() and .gen_range() methods
- rand::distr::Uniform::new() returns Result<Uniform, UniformError> rather than infallible construction or panicking
- rand::seq::IndexedRandom provides choose and choose_multiple on slices replacing rand::seq::SliceRandom
- rand::distr::SampleString with Alphanumeric generates random ASCII strings
- SeedableRng::seed_from_u64 produces deterministic repeatable random sequences across generator instances
