Refactor codebase to resolve clippy warnings and update CI/Docs

- Fixed over 400 clippy lints across core and built-in modules
- Removed redundant clones on Copy types (Gc pointers) and fixed borrow issues
- Updated function signatures from &Vec to slice references for better performance
- Synchronized all test cases and JS scripts with modern idioms and resolved lints
- Updated README to reflect feature-gate requirements for the 'os' module
- Enhanced CI workflow to test all targets and multiple feature configurations
