This commit introduces two main changes:
1. A new program `showAll.go` that uses `wmctrl` to find all
running terminals and print their geometry and workspace. This
provides the core functionality for saving window positions.
2. The existing `stuff.go` program has been fixed to correctly
find and modify a terminal window. It now targets a generic
"Terminal" window and correctly retrieves its geometry,
allowing it to move and resize it successfully.
