Refactor PATH environment variable update in install.ps1

andy1li · andy1li · commit b7b26288d22d · 2026-01-12T13:32:39.000+09:00
Modified the logic for updating the user's PATH environment variable in the install.ps1 script. The change ensures that the PATH is set correctly whether or not it already contains a value, improving the installation process for the CodeCrafters CLI on Windows.
