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
