- Added numerous new fixers and rules (e.g., prefer numeric literals, no undef init, no useless computed key, directive spacing, IIFE wrapping, dot location, yoda style).
- Fixed several linting false positives/negatives and conflicts, including object shorthand consistency, unused vars, indent handling, mixed spaces/tabs, extra parentheses, and error template handling with stdin.
- Updated and corrected documentation such as contributor onboarding steps, ES8 references, reflect guidance, object shorthand typo, and issue template formatting.
