Refactor cursor package handling in home-manager configuration

- Simplified the cursor package selection by removing the deprecated `cursor-agent` option and retaining only `cursor-cli`.
- Updated the activation script to remove the broken `cursor-agent` symlink, ensuring proper resolution to `cursor-cli`.
- Adjusted the configuration to reflect these changes in the Nix IDE tools integration.
