Add token, hex, and pin helpers for the common ASCII string formats already represented by the crate's built-in charsets. These methods keep frequent use cases concise while continuing to route through string_from, so callers still get the same uniform per-character sampling behavior. Avoid adding a password preset in this change. Password generation implies policy choices around symbols, ambiguous characters, and service-specific constraints, while these presets are direct names for existing alphabets. Document every preset with doctested examples and add a runnable presets example. Update the demo to show both presets and custom string generation. Test Plan: - cargo test - cargo clippy - cargo clippy --benches - cargo clippy --tests - cargo +nightly fmt Refs: IDEAS.md ergonomics backlog
