- Implemented customization of serialization for languageOptions and a new CLI flag to pass on unpruned suppressions.
- Fixed multiple bugs (removed configured globals from implicit scope, updated context.report types, avoided false positives in no‑unassigned‑vars, corrected curly types) and refreshed documentation with examples and clarifications.
