Subject: [PATCH] add GOOS=js (wasm) build support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Provide the tty platform layer for the js build tag so the package
compiles for browser (wasm) targets: init/restore/close are no-ops
(there is no terminal to configure) and openInputTTY reports that no
controlling terminal exists — callers supply input through explicit
readers. Lets TUI libraries that depend on this package build
unchanged for wasm.
