feat: Remove obsolete binaries and update module dependencies

- Deleted outdated binary files for Windows, Linux, and macOS platforms to streamline the project.
- Updated `go.mod` to change the module path to `cursor-id-modifier` and adjusted dependency versions for `github.com/fatih/color` and `golang.org/x/sys`.
- Modified `install.sh` to reflect new binary naming conventions and download URLs.
- Cleaned up whitespace in `main.go` for improved code readability.

This commit focuses on cleaning up the project structure and ensuring dependencies are up-to-date.
