Add hemx-lsp for stdio LSP diagnostics, completion, and hover while preserving HTML editor tooling for .heml files. Teach hemx-build to expose generated target and derive-known template context facts, including simple h-for locals, so editor help comes from build-owned facts instead of editor-only parsers. Wire VS Code/Cursor and Neovim documentation and extend the Workout exemplar with a real h-for plan loop for end-to-end proof.

Add a runnable phone-first workout example that keeps local workout truth as commands, domain events, and projections, routes export through the host capability boundary, and documents how to open it in the browser.

Introduce hemx-host with typed capability manifests, calls, events, host-check failures, reusable browser/PWA and native-shell profiles, and a tiny optional browser adapter for haptics/share that returns host events without DOM mutation.
