Expand the µRust's Option implementation with more utility functions from the Rust std documentation, e.g.unwrap_or implementation
- map / and_then (flatmap) — monadic chaining; eliminates nested match reasoning
- unwrap_or_default — default-value fallback
- zip — combine two Options
- flatten — Option<Option> → Option
- map / and_then for Result — error-propagation reasoning
