feat: Implement Clone trait for JobQueue structs v1.8.1

- Add manual Clone implementation for JobQueue<DB> to handle generic database types
- Fix clippy warnings by removing unnecessary .clone() calls on Copy types (JobStatus)
- Add comprehensive test for Clone trait functionality
- Update crate version to 1.8.1
- Improve developer ergonomics when sharing queue instances across components

+## [1.8.1] - 2025-07-12
+
+### Added
+- **🔄 Clone Trait Implementation**
+  - Implemented `Clone` trait for `JobQueue<DB>` struct for better ergonomics
+  - Added manual `Clone` implementation to handle generic database types
+  - `TestQueue` already had `Clone` support (no changes needed)
+  - Improved developer experience when sharing queue instances across application components
+
+### Fixed
+- **🐛 Code Quality Improvements**
+  - Fixed unnecessary `.clone()` calls on `JobStatus` enum (implements `Copy`)
+  - Resolved clippy warnings related to `clone_on_copy`
+  - Enhanced code efficiency by using copy semantics where appropriate
+
 ## [1.8.0] - 2025-07-07
