Add array length syntax ${arr[#]}
Map read path now expands variables before splitting on ., fixing map "$node" with dotted paths
Map assignment path uses quote-aware token splitting, enabling quoted keys like "--type="
Completion errors now display above prompt instead of being overwritten
Fix nested if/fi parser bug when closing keywords appear on separate lines
Add QuoteState enum, replacing ad-hoc quote tracking booleans across lexer, highlighter, and expansion
Add split_tk_at/split_tk for quote-aware token splitting with span preservation
Refactor setup_builtin to accept optional argv for deferred expansion
Add ariadne dependency (not yet wired up)
