fix(rust): resolve edition2024 dependency issue and compilation errors

- Pin image crate to 0.25.1 to avoid edition2024 requirement from moxcms
- Add missing installation_type field to ClaudeInstallation struct
- Update Cargo.lock with compatible dependencies

The moxcms-0.7.6 crate requires edition2024 which is not available in
stable Rust 1.82. Pinning the image crate to 0.25.1 avoids this
dependency while maintaining functionality.
