The documented wheel build wrapper calls a removed release directory

## Problem

The development guide directs macOS/Linux users to `tools/build`. After building wheels, that wrapper attempts to enter `qt/release` and invoke `build.sh`, but that release path no longer exists. The wrapper reports failure despite generated wheels being available. The Windows wrapper also bypasses the current project recipe.

## Expected behavior

The documented wheel command should finish successfully after producing wheels, without invoking removed release scripts.

## Environment

Observed while developing on Apple Silicon macOS at 9753998c5; the affected code is still present in upstream main at 93bd38288. A focused fix and validation are prepared.
