fix(tauri): drop web CLI; watch dev server; tidy docs workspace

Remove the Rust \web\ subcommand and HTTP stack—browser dev stays on Vite
(\dev:*-web\). Keep \server\ plus default window mode.

Run \dev:server\ via \cargo watch\ so Rust changes rebuild headless RPC like
tauri dev. Trim workspace Cargo.toml (remove stray member) and lockfile deps.

README: document all three dev:*-server scripts and cargo-watch install.
