fix(deps): update rust crate rand to 0.9 (#38)

* fix(deps): update rust crate rand to 0.9

* fix(deps): update rust crate rand to 0.9

Migrate to rand 0.9 API changes:
- Replace `rand::thread_rng()` with `rand::rng()`
- Replace `rng.gen()` with `rng.random()`

These renames were made in rand 0.9 to avoid conflict with the
`gen` keyword in Rust 2024 edition.
