Track the LScript changes since the grammar was first written: - some, ok and err are reserved prefix operators and wrapper patterns; the old |.some/|.ok/|.err forms and postfix/prefix ! are rejected - function literal inputs may omit their type annotation, and tuple components may omit theirs; an empty typed tuple pattern is now just the unit pattern - migrate fixtures, corpus, queries, CST contract and Rust tests Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
