Pull request overview

This PR modernizes iptools for stricter parsing and higher performance, expands allocation-free iteration APIs for IpRange, and splits the WebAssembly demo bindings into a separate iptools-wasm workspace crate while keeping the core crate wasm-compatible.

Changes:

• Tighten IPv4/IPv6 parsing/validation rules (strict dotted-quad IPv4; stricter IPv6 compression + mixed-tail parsing) and gate regex-based validators behind the std feature.
• Add faster numeric range/bounds helpers and iteration/formatting adapters (*_bounds, next_addr, for_each_addr, addrs_view, contains_strict, iterator shortcuts).
• Move wasm-bindgen bindings + demo glue into crates/iptools-wasm, update docs/CI/workspace accordingly.
