#!/bin/bash
# One-liner installer for IDEasy.
# Usage: bash -c "$(curl -fsSL https://raw.githubusercontent.com/devonfw/IDEasy/main/install.sh)"
#
# What it does:
#   1. Detects your OS (mac/linux) and architecture (x64/arm64)
#   2. Fetches the latest release version from GitHub
#   3. Downloads and extracts the correct archive to a temp directory
#   4. Runs the setup script
#   5. Cleans up the temp directory
#
# On Windows use Git Bash (comes with Git for Windows).
# Prerequisites: git, curl, tar
