Run the real hel core in the browser via WebAssembly, replacing the plain-JS
ooke.github.io/sk reimplementation so the web and the CLI share one generator.
- hel core: new storage module (native fs / wasm localStorage) backs
init/source/dump/correct; the pipe and pb branches are gated out of wasm;
the wasm editor is completed (EditorRef) and its password prompt no longer
blocks the single JS thread (synchronous hel_get_password instead of a
thread::sleep poll).
- helwasm: hel_load_script for bulk import, a panic hook in hel_init, dropped
the ok_add / web-sys leftovers; build.sh runs wasm-bindgen into a committed
pkg/ so GitHub Pages can serve the static dir with no CI.
- UI: rewritten index.html + style.css in the kaizenkodo.org style — responsive,
masked-but-copyable passwords with click-to-reveal, a quick-generate card plus
a full command console, localStorage persistence, and paste import/export.
