<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Upgrade/Install: Introduce a `move_dir()` function.
This replaces the `copy_dir()` usage in `WP_Upgrader::install_package()` and aims to avoid PHP timeout issues when installing or updating large plugins on slower systems like Vagrant or the WP Docker test environment.
The new function attempts a native PHP `rename()` function first and falls back to the previous `copy_dir()`.
