Add WebAssembly support with feature flags and conditional compilation, upgrade version to 0.5.0

- Add native and wasm feature flags to machi/Cargo.toml: native (default) enables tokio/full for native platforms, wasm enables getrandom/wasm_js, chrono/wasmbind, and uuid/js for WebAssembly
- Configure workspace dependencies for WASM compatibility: disable default features for chrono and tokio, add explicit feature selections
- Add getrandom dependency as optional workspace dependency for WASM random
