Add a platform-specific implementation to allow the module to compile for GOOS=js and GOARCH=wasm, without providing terminal functionality.

Terminal detection reports false, and unsupported operations return errors instead of silently succeeding. This is particularly important for operations such as disabling terminal echo, where silently ignoring the request could expose sensitive input.

Actual WebAssembly terminal support can be considered separately.

🟢 Approval recommended

The platform guards and stubs match the compilation-only scope and explicitly reject unsupported terminal operations.

No open issues 🎉

• Add makeRaw stub for js/wasm builds

🟢 Approval recommended

The build constraints and stubs consistently provide compile-only support without silently accepting unsupported terminal operations.

Had a quick peek at golang.org/x/term (parts of which we may want to wrap in future instead of golang.org/x/sys directly); I'll make some minor changes (naming of the stub files, error-message) to align with it, so that a future rewrite using golang.org/x/term will be less eventful.

Done (for now)
