Add OsRandom::fill_bytes so callers can fill a byte slice without importing std::io::Read. This keeps the common raw-byte use case close to the rest of the crate's typed convenience API while still forwarding to the same /dev/urandom handle. Implement Default for OsRandom as the infallible convenience constructor. The fallible OsRandom::try_new API remains the right choice when the caller wants to handle an unavailable operating-system randomness source explicitly. Document the public constructors and byte-fill helper with working examples, and add a runnable bytes example for the top-level workflow. Test Plan: - cargo test - cargo clippy - cargo clippy --benches - cargo clippy --tests - cargo +nightly fmt Refs: IDEAS.md ergonomics backlog
