Fix missing installation_type field in ClaudeInstallation struct

- Add missing installation_type field to ClaudeInstallation initialization in find_nvm_installations() function at line 222
- This field is required by the struct definition but was omitted from one instance in the NVM discovery code
- The missing field caused Rust compilation to fail with error E0063 during tauri build
- Set installation_type to InstallationType::System to match other NVM installations in the same function
- Fixes build failure for aarch64-apple-darwin target and other platforms
